Package/module semantics changed during 2.6/3.0.  I think it might have
something to do with that.  Hopefully some of the py3 work will fix these
problems too.

Actually, I think it might also be a buildout bug.  It seems buildout uses
the sys.path variable to add paths to the python interpreter.  Whereas the
'proper' way is to use the PYTHONPATH environment imho.  Since modifying
sys.path does not affect sub processes paths.  It seems numpy uses a sub
process in the install?  Or maybe buildout/python2.6 use a subprocess.  Or
with 2.5 already having a numpy installed (on osx), then perhaps it was
using the old numpy.distutils already installed to do the install.

Anyway, that's my findings so far.  Not sure if I'll look into it more.
