0.99.1.1 build attempts to import non-existing wx

Hi All -

I just downloaded 0.99.1.1 and I'm finding this error:

[esheldon@...2842... matplotlib-0.99.1.1] python setup.py build

Seems to recognize that wx is not found but then tries to import it
anyway. This is due to the variable options['build_wxagg'] being
True. When I build 0.99.0 this variable has the value 'auto' and wx
is not imported. This seems to be a bug, but perhaps I'm missing
something.

thanks,
Erin Sheldon

FYI, there is the setup when building 0.99.0
