I've used uClibc-0.9.29.tar.bz2 and also the uClibc snapshot (from Oct 
2.)  Is that what you are asking for?

Both versions gave the same problem with Python, but the snapshot 
version fixed similar problems with sudo and the ssh family of executables.

Hmmm, I just scrounged around and manually downloaded the old version 
from somewhere.

I'm not at all sure that I'm ready, much less sufficiently experienced 
in the buildroot world, to advance the patches and stuff for sudo to the 
current version from the www.courtesan.com site.

Here's what I've been using, assuming that email doesn't word wrap it 
into oblivion:
