yes

Good, so the failure was due to the Mac related bug in Python 2.2.

It's not too bad:)

With Python 2.3b1+ (from yesterdays Python CVS) I also get
KeyError's like

======================================================================
ERROR: check_chebyc (test_basic.test_chebyc)
----------------------------------------------------------------------
Traceback (most recent call last):
  File
"/usr/local/apps/SciPy-CVS/lib/python/scipy/special/tests/test_basic.py",
line 214, in check_chebyc
    chebc = chebyc(1)(.2)
  File "/usr/local/apps/SciPy-CVS/lib/python/scipy/special/orthogonal.py",
line 398, in chebyc
    p = p * 2.0/p(2)
  File "/usr/local/apps/SciPy-CVS/lib/python/scipy_base/polynomial.py",
line 445, in __getattr__
    raise KeyError
KeyError

I'll see if it can be fixed for Py2.3...

But as for other failures like numerous AssertionErrors in testing
scipy_base and stats, I don't get them under Linux.

Could you investigate the errors in scipy_base testing?
You can do that separately from building scipy when changing the
scipy_base code:

  cd scipy/scipy_core
  python setup.py install

  >>> import scipy_base
  >>> scipy_base.test(1)
