Yes I have, openopt works incorrectly, you could check it by yourself

 >>> from scikits.openopt import NLP
 >>> NLP(lambda x:x**2,4).solve('ralg')

OO Error:incorrect solver is called, maybe the solver "ralg" is not 
installed. Maybe setting p.debug=1 could specify the matter more precisely

I guess now "python setup.py install" forms Python egg (previously there 
was a simple copying of Python files to installation directory), and 
openopt can't find path to a solver. Dictionary with the paths to 
*_oo.py files  is formed via os.walk() during start of openopt session, 
and os.walk can't handle situation with eggs.
