setup.py wasn't up to date.

Does it work now?

Works for me now. I got however this exception when running the tests (using
mpmath.runtests()):

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "mpmath/__init__.py", line 352, in runtests
    tests.testit(importdir, testdir)
  File "mpmath/tests/runtests.py", line 140, in testit
    sys.path.remove(importdir)
ValueError: list.remove(x): x not in list

This is because for some reason importdir misses '/mpmath/tests' at the end.

Does this indicate a problem or can we just wrap the cleanup code in try-except?

It's not really a problem, sys.path might be "messy" concerning 1 entry 
afterwards. 
I just don't understand why this happens.

If we add a try block we just hide the exception.

The question is if it's just some spurious effect, or whether there is some 
problem
with the paths that could affect other things.
