Thanks for responding Charles,

I have tried code similar to yours that I found in the 
documentation, but I keep getting errors like this:

Traceback:
File 
"/usr/local/lib/python2.6/dist-packages/django/core/handlers/base.py" 
in get_response
   100.                     response = callback(request, 
*callback_args, **callback_kwargs)

preamble

File "/usr/lib/pymodules/python2.6/pyx/text.py" in execute
   1040.                 raise TexResultError("unhandled 
TeX response (might be an error)", self)

Exception Type: TexResultError at /test_pyx_pdf/
Exception Value: unhandled TeX response (might be an 
error)
The expression passed to TeX was:
   \DeclareFixedFont{\LittleFont}{T1}{ptm}{b}{it}{0.75in}%
   \PyXInput{6}%
After parsing the return message from TeX, the following 
was left:
   *(/usr/share/texmf-texlive/tex/latex/psnfss/t1ptm.fd)
   kpathsea: Running mktextfm ptmbi8t
   mktextfm: Running mf-nowin -progname=mf \mode:=ljfour; 
mag:=1; nonstopmode; input ptmbi8t
   This is METAFONT, Version 2.718281 (TeX Live 
2009/Debian)
   
   (cut after 5 lines, increase errordebug for more 
output)
