Hello All,

  I've been using zope and matplotlib for some time now, and I want to
connect them. I'am using the example code from page:
http://www.scipy.org/Cookbook/Matplotlib/Matplotlib_and_Zope ,
but whenever I try to import matplotlib, and/or pylab packages i get
this error from zope:

Error Type: RuntimeError
Error Value: '/' is not a writable dir; you must set environment
variable HOME to be a writable dir

Have You got any ideas, on what might go wrong?
Is it a problem with matplotlib itself? Have anyone had the same issue?

 I'am using matplotlib 0.87.4, and zope 2.9.5 with python 2.4.3 on
gentoo linux box.

Thanks in advance for any help.
