[Matplotlib-users] Errors, warnings, fonts and py2exe

[Armando S. L. <ars...@gm...>]

Hello, I'm having a weird problem with matplotlib not finding fonts when
being used from a py2exe packed program. The weird thing is that the
program works fine on some computers, gives an annoying warning in others
(but otherwise keeps working and plots things ok) or gives an error (and no
plot is produced) in others.

A strange thing I noticed is that I'm using python 2.5 and one of the
warnings is referring to python 2.6, so somehow it must be confusing itself
with a python version installed in that computer.

Can somebody help?

Thanks,
Armando.
