Hi Marek,
Never heard of matplotlib.  But your traceback is saying that the 
product is trying to write to root - without sufficient permission.  I'd 
look at the source (see _get_configdir) and see if its reading some sort 
of config file or maybe its parsing the enviromental var HOME..  You 
probably can modify that.  Anyway, writing to "/" doesnt seem to be a 
good idea in any case.

You have set variable "HOME"? 

Best,
David H
