[Matplotlib-users] Error with PDF output with usetex

[Jeff K. <kl...@wi...>]

Hello all,

I am running Mac OS X 10.7 Lion with matplotlib 1.0.1 and the MacTex
2011 distrubution.

I am able to run the tex_demo.py with no problems and I can create
output files using the Agg backend.  When I try to use the PDF
backend, however, I get an error which stems from dviread.py (pasted
below).  Any thoughts on what could be going wrong?

Thanks!
Jeff
