Looks like you've done this already.  Good.  I just checked on test level 10 and
everything passes on RH 7.1, even all the weave tests.

I do have one problem though:

>>> import clapack
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: ./clapack.so: undefined symbol: clapack_sgesv

This makes no sense because I checked my liblapack.a, and the symbol is defined.
Anyone else seen this?  Removing clapack.so gets everything to work smashingly.
Anyway, I'll try to track it down.

Not sure about this.  I'll get them from him, and put them back up in a public

Cool -- but what are the weave failures?  I don't get any failures when testing
with the latest CVS, Python2.2b2 on RH 7.1.  It looks like multiple platforms
are having problems with weave.  I'll post a separate message for this and try
to gather up all the issues under one thread.
