# This script builds the binaries and libraries needed by src2pkg to function properly. The src2pkg package
# contains no binaries when first installed, so this script  must be run to setup src2pkg for use on your system.
# This method is used to ensure that the binaries and libraries work properly on your system, no matter
# which architecture and OS version you are running. It also provides a check to be sure that your system
# has the basic tools needed to compile software. Otherwise src2pkg would not work anyway.
