Hi!

Matplotlib saves some stuff into  a configuration dir. Take a look at
the __init__.py file in site-packages/matplotlib (or where your
installation lives). There are several environment variabels checked
where a .matplotlib folder will be created. Try unsetting HOME, than
probably TMP will be used and this should be writable in any case. I
don't know whether the creation of the configuration folder can be
turned off.

Hope that helps! Bernhard
