[IronPython] sympy on IP 2.6B2

[Jeffrey Sax]

According to the archives, some version of sympy worked on IP 1.x at some
point in the distant past. Now, with the latest version of both (sympy 0.6.5
on IronPython 2.6.B2), I get this:

PS C:\Program Files (x86)\IronPython 2.6> .\ipy.exe

Note also that when I retry the import, I get a different error message:

>>> from sympy import Symbol, cos
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\Program Files

Any idea what's going on here?

Thanks,
