It appears that the following replacement of _get_afm_filenames
works. I'm a python learner so that may lead to other bugs. :-)

     def _get_afm_filenames(self):
         paths = [os.path.join(distutils.sysconfig.PREFIX, 'share', 
'matplotlib')]
         if os.environ.has_key('AFMPATH'):
             afmpath = os.environ['AFMPATH']
             ### if afmpath.find(';')>0: #win32 style
             ###    paths.extend(afmpath.split(';'))
             ### elif afmpath.find(':')>0: # unix style
             ###    paths.extend(afmpath.split(':'))
             ### else:
         paths.append(afmpath)
	fnames = []
         fnames = [fname for fname in get_recursive_filelist(paths)
                   if fname.lower().find('.afm')>0 and
                      os.path.exists(fname)]
	### start debug
	#print paths
    	#print fnames
	###raw_input("Hit enter to continue -->")
	### end debug
         return fnames

I'm going to sleep now. :-)

Good day,
