Apparently the problem here (what I should have thought of first) is
that the directory containing foo.py is not in my sage python path.
The surprising (to me) part, and the reason I didn't think of it, is
that this breaks things even if the file I'm testing is foo.py and I
try 'from foo import *'. So it seems the only remedy (for now, since
I understand SAGE overrides my PYTHONPATH variable) is something like
sage: import sys
sage: mypath= '/mydir/'
sage: if mypath not in sys.path: sys.path.append(mypath)
where /mydir/ is the path to foo.py. This works, but doesn't seem
like a good solution, and is, I think, another good reason to allow
the user to modify sage's startup pythonpath.
