First of all, this stuff is for people who enjoy risky and dangerous stuff.
If you don't like running with scissors, then probably you should stay away.
If you don't like walking on the dark side of the moon, you should definitely
stay away  ;-)   Seriously, I did all of this for MY OWN USE, and since it 
turned out okay (for the most part), I'm throwing it out onto the internet.
Feedback is welcome, but due to a major lack of extra time these days, I may
not respond timely or even at all.  If these packages cause your system to 
be unusable and/or cause hair to grow from the soles of your feet, that sucks
for you.  Send pictures of the hair though - morbid curiosity compels me to
look at that.

A changelog is at the very bottom of this file.

BUILD ORDER:

 0. /sbin/removepkg xfce xfce4-power-manager xfce4-notifyd
 1. ORBit2
 2. GConf
 3. libtasn1
 3. libgnome-keyring
 5. gnome-keyring
 6. libatasmart
 7. sg3_utils
 8. udisks
 9. upower
10. glade3
11. libdaemon
12. libunique
13. avahi
14. libproxy
15. libsoup
16. gnome-disk-utility
17. gvfs
18. xfce
19. thunar-volman
20. Terminal
21. orage
22. xfce4-mixer
23. xfce4-power-manager
24. xfce4-notifyd

media-player-info is not strictly needed by any of this, but it replaces
  the ipod and similar type device database previously in hal, so we will 
  need it...

libatasmart and sg3_utils are needed by udisks.

Terminal, mousepad, orage, xfce4-mixer, thunar-volman, and xfce4-power-manager
  are now standalone packages (some already were, and some were bundled with
  the main xfce package before).  xfce4-power-manager needs upower.

libxfce4ui optionally uses glade, so let's add glade3.  

gvfs requires gnome-disk-utility if you want to mount disks with it.
  gnome-disk-utility requires libunique and avahi.  avahi requires libdaemon.
  gvfs also requires libsoup, which requires libproxy and gnome-keyring,
  which requires libtasn1.

All that said, the avahi dep in gnome-disk-utility doesn't seem like it 
  should be strictly required.  There is a "--disable-remote-access"
  flag to configure that perhaps was supposed to make avahi optional, but
  it doesn't work that way.  Maybe that was an accident (untested path in
  the code?), or maybe it's on purpose - if someone wants to poke at it 
  and try to find out, feel free.


#### Xfce package notes ####

glade3 was added for libxfce4ui

xfconf can use perl-extutils-{depends,pkgconfig} and perl-glib, but I
  don't notice any missing features, so probably not worth the addition

Several modules are no longer part of "core" - and while that in itself
  wasn't enough for me to take one out of the main xfce package, there
  are several things that were formerly part of the main package but won't
  be any more...

Sun Dec  5 08:23:47 UTC 2010
  Rebuilt Terminal

Sun Dec  5 22:48:11 UTC 2010
  Upgraded main xfce package to 4.8.0pre2
    - this upgrades Thunar, garcon, tumbler, xfce4-panel, xfce4-settings,
      xfce-utils, xfdesktop, xfwm4
    - this now calls ck-launch-session to start xfce4-session in xinitrc
      if we're not running from a graphical login manager
    - fixed libcanberra usage (xfce4-settings rather than xfce4-session
      needs it, and it needed a patch from xfce4-settings git)
    - add gnome-keyring support to xfce4-session
  Upgraded thunar-volman to 0.5.3

Mon Dec 20 02:13:30 UTC 2010
  Removed libnotify (use -current package instead)

Mon Dec 20 05:18:56 UTC 2010
  Upgraded libtasn1 to 2.9
  Upgraded libsoup to 2.32.2
  Rebuilt gnome-disk-utility to autostart its stuff in everything
    but KDE now
  Added libgnome-keyring and upgraded gnome-keyring to 2.32.1
    - let's see how this works...  It seems fine here, and in fact, I 
      decided to let gnome-keyring be my ssh and gpg agent.  It seems 
      as simple as checking the "Launch GNOME services on startup" box 
      in the Advanced tab of Xfce's "Session and Startup" preferences.

Mon Jan  3 04:43:15 UTC 2011
  Upgraded xfce to 4.8.0_pre3

  Upgraded upower and xfce4-power-manager

Sun Jan 16 21:09:06 UTC 2011
  Upgraded xfce to 4.8
  Removed sound-theme-freedesktop and libcanberra: I could never get the
    sound settings to work, so unless someone can tell me where I went
    wrong, I see no point in building this stuff.
  Upgraded orage to 4.8.0
  Upgraded thunar-volman to 0.6.0

Mon Jan 17 21:14:51 UTC 2011
  Rebuilt gnome-disk-utility to remove the hardcoded nautilus usage;
    now we'll use xdg-open instead.  
    Thanks to ssuominen, one of my Gentoo dev friends :-)
