[SciPy-user] Bug in openopt: objFunrelated

For a user supplied gradient that is not iterable, user_df in
objFunRelated.py returns an UnboundLocalError since user_df_func in
reference before it is assigned.
Looking at the code, this is obvious.
Suggest a line after 116 as an else to the if on 112:
else: user_df_func = p.user.df
When openopt is compiled with this change, the solver runs without
crashing, and my NLP runs to an approximate solution on all the major
solvers. I see no reason not to adopt this change.
Cheers,
Mclean
