import pylab (from matplotlib) fails

[elfnor]

Hi

Importing the pylab module from matplotlib fails

>>> import pylab
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
File "E:\PortablePython_1.1_py2.5.4\App\lib\site-packages\pylab.py",
line 1, in <module>

pickle.dump(data, fh)
IOError: [Errno 2] No such file or directory


It seems the font_maanger module needs to read/write files to the
directory returned by
>>> matplotlib.get_configdir()
'H:\\.matplotlib'

which dosen't exist in a portable install.

The location of this directory can be changed with the MPLCONFIGDIR
environment variable in a fixed install.

Any clues?
