Hi Jim!

Right, the problem with `ls` is an incompatibility between old kernels
(older than 2.6.36) and new glibc built against newer kernel headers.
I've built an O2-compatible kernel (version 3.1.0-r2~) and put it
here: http://dev.gentoo.org/~mattst88/sgi-o2/

I haven't tested it, so if you run into trouble, please let me know
and I'll make some changes.

I'm very glad to see someone trying to use my stages. Please note that
before you rebuild gcc, you should patch
/usr/portage/eclass/toolchain.eclass with the attached patch in this
bug report: https://bugs.gentoo.org/show_bug.cgi?id=358149

I'm not sure, but perhaps the problem about sashARCS/sash64 is fixed
by using the vmlinux.32 I posted?

You can probably get help faster in the #gentoo-mips IRC channel on
Freenode as well. I'd be happy to help.

Thanks, and let me know how it goes,
Matt
