Re: [gentoo-dev] Moving functionality out of portage and into the tree

[Hasan Khalil]

Amen. Having to wait for a portage upgrade halts development for too 
long, particularly with the Gentoo for Mac OS X project (as well as the 
BSD project), both of which will need small changes to do* scripts, etc 
(dolib, anyone?).
