any Python equivalent of Math::Polynomial::Solve?

The GNU Scientific Library has a nice root finder for polynomials with 
real coefficients.  I have wrapped this with Pyrex to work with my 
ratfun module see:

http://calcrpnpy.sourceforge.net/ratfun.html

If this will suit your needs, I can send you an alpha release of the 
package with the root finder.  It is not pure Python.  I requires Pyrex 
and a C compiler to install.  My guess is that it will work on OSX as 
well as it does on Linux.  This functionality will be included in the 
next release of the ratfun package but I still have to unit test a 
number of components and update the documentation.  Consequently, an 
official release will not happen soon.
