Re: [matplotlib-devel] ANN matplotlib-0.53

I just uninstalled the 0.53b release and installed 0.53
There's still a problem on my Win98 system, but now it seems related to the
new font manager:

>>> from matplotlib.matlab import *

Traceback (most recent call last):

    from matplotlib.matlab import *

    if not local:
