[SciPy-user] umfpack and building scipy from source

I may have had the misfortune of checking out of svn last night while
numpy and scipy were out of sync.  I re-did my svn checkout just now
and numpy didn't change, but scipy went from version 2339 to 2342.  I
now get fewer errors.  I also did a python setup.py clean for each
before rebuilding and deleted site-packages/numpy and /scipy before
rebuilding.  I am still getting an error from scipy.test that it is
built against a different version of the API (see below).  Is this
detrimental?

Thanks,

Ryan
