My TODO list:

1. A local copy of PORTDIR should be created in CONST.TMPDIR + GRS name.  This is
to prevent wierdness in case /usr/portage changes during a run.

2. Upon building a system we should make use of the binpkgs in CONST.TMPDIR + GRS name
as a time saver.  This is something to go into the build scripts in the GRS repo and not
in the GRS suite.
