I do not think this is a very large repository.

I have MacBook Pro with 4G of RAM. Attempted to re-do the upgrade with only iTerm running (and base OS services) and still get the Memory error (which likes OOM).

I dug around in groupcompress.py a little bit, but not familiar enough with things at that layer to do more then appreciate all of the hard work done at those levels.

Trivial repositories upgrade fine.

Any mentoring available?

Same issue Mac Pro with 8G RAM, will attempt on ubuntu hardy and 8G RAM and report back here.

[Bob Tanner (tanner)]

Got the upgrade to work on FreeBSD and python-2.5.2. Could the problem be inside python-2.6.x?

Adding --version for details.

Resolves this problem.

This would have been the set of bugs spiv resolved very late in 2.0.0. then, I think. Thanks for checking.
