Re: [gentoo-ppc-user] Gentoo on NuBus

[Andrew Gaffney]

Success!!! I finally realized why it wouldn't compile correctly. I've 
gotten so used to portage that the part of my brain used for tracking 
down dependencies had been shut off. I need to get the lzo and ucl 
compression libraries. The live.gcloop file was compressed using the ucl 
compression format. I was able to mount it on my x86 box. Now I'm going 
to try cross-compiling the module for my nubus kernel.
