Hi,

I've been testing my matplotlib 0.86.2 installation on Fedora Core 4 and hit a problem I can't solve. If I do "python tex_demo.py" in the examples directory it seems to hang up. A quick "ps faxw" and a bit of digging shows that the problem is that on my installation of tetex, TeX isn't recognizing \rmfamily:

freyer:~/.matplotlib/tex.cache> tex 0885e19fbc15d1bc2b5e1d3ac6018bee.tex

This is TeX, Version 3.141592 (Web2C 7.5.4)

(./0885e19fbc15d1bc2b5e1d3ac6018bee.tex

! Undefined control sequence.

l.5 {\rmfamily

\TeX\ is Number $\displaystyle\sum_{n=1}^\infty\frac{-e^{i\pi...? x

What is the problem here? I searched the mailing list and no one else seems to be having this trouble, so obviously it's my fault, but I can't quite figure out how.
