Sympy duplicates the python library 'mpmath'. This is against Fedora guidelines, unless an exception has been obtained from FESCo. mpmath must be removed from the sympy package and sympy must be patched to use the python-mpmath package, instead.
I've patched around this and remove the mpmath directories in %prep. I've done some minimal testing with the pidigits.py example (which uses mpmath) and it seems to work fine. Built in rawhide: http://koji.fedoraproject.org/koji/taskinfo?taskID=1988253 Closing.
