[gentoo-catalyst] Catalyst tree move code changes. [1 of 4]

[Brian Dolbec <dolsen@gentoo.org>]

[-- Attachment #1.1: Type: text/plain, Size: 505 bytes --]

This is the first of some untested (but they compile without errors)
patches to catalyst for the pending default tree location changes.

My current gentoo machine is somewhat limited in capability (memory
shortage, only moderate cpu horespower) for doing proper testing.  But I
will try and get it setup better to do some test runs for changes.

I can also push my catalyst git repo to my dev space for you to checkout
and do some tests on if you like.
