Aiiih! No woorries maaan!
Had the same problem.. HAve you got Kernel sources installed?
I just installed the Kernel sources.. although still have problems, maybe you won't.
% rpm -qa | grep kernel
That showed me I had two kernels, and no source for either.
SO installed sources, through Mandrake Control Center (Should be on installation CD's or try finding out Kernel version.. I forget how.. look in /sbin, I think for the kernel version command (running kernel, that is)).
Then they (both src.rpm and tar) compiled ok.
Installed rpm, and tar.. nowt.. I ran Tuxracer to see.. still like mud!
Keep it cool, keep it grroooovie...
