Thanks for all the feedback. Let me know when it's fixed, I'll retry
it again and then I'll also try to figure out the metaclasses problem
-- as Alex suggested, it can be a problem in sympy, but sympy works on
all cpython 2.4, 2.5 and 2.6, so definitely jython should not just
throw some java exception.
Getting sympy to import is just the first thing. The real fun will
begin when running the actuall tests, so I am sure more problems will
popup. But generally, jython seems to be in a pretty good shape. Btw,
pypy had similar problems too in the past and ironpython also cannot
import sympy.

P.S. I am going to the google mentors summit and I'll be in the bay
area from 27-29. If some of you are be around, let me know.
