[PyX-devel] Weird font crash under RedHat 9.0

[Fernando P. <Fer...@co...>]

Hi all,

I have some code which works perfectly OK in a Fedora box, yet is crashing 
when run on a RH9 machine.  The final exception is:

   File "/home/fperez/usr/local/lib/python/pyx/dvifile.py", line 636, in __init__
     raise RuntimeError("no information for font '%s' found in font mapping 
file, aborting" % name)
RuntimeError: no information for font 'cmmi10' found in font mapping file, 
aborting

Both the RH9 and the Fedora boxes are heavily used for latex writing, so I 
know the fonts are there on both.  I tried building PyX itself  (I'm running 
0.6.2) on both machines, and the results don't change.

I would very much appreciate any pointers.  I'm including a very detailed 
traceback below, in case it helps.

Thanks in advance,

Fernando.
