Hey!

See my e-mail or "Boyed Stephen Smith Jr.'s mail". Don't use 
USE="blabla" emerge package or ACCEPT_KEYWORDS="..", because these 
settings are just temporary and when will only be applied to this one 
emerge.

I haven't used -k (--usepkg) yet however the man page tells me that -k 
means, that precompiled packages should be used. So your USE flag does 
not take any effect.

Btw.: You shouldn't say that this problem is fixed as you just have used 
something precompiled and preconfigured. You should better digg deeper 
into emerge and USE flags. Otherwise you will never understand portage 
which is _essential_ for understanding and using Gentoo Linux. This is 
just and advice...

Best Regards Jay
