Yes, that's correct.  Thanks for catching it.

Matplotlib comes with a set of AFM files.  Did you do a normal 

  > python setup.py install

with matplotlib?  If so, distutils should put the files in a place
where matplotlib can find them even w/o setting AFMPATH (eg,
/usr/local/share/matplotlib or /usr/share/matplotlib).  If they are
not there, then my guess is something went funny with your install.
These files reside in the src distribution in the dir
matplotlib/fonts/afm, so you can get them there and set AFMPATH
accordingly.

The easiest way to find the AFM fonts on your system is to do

  > locate afm | less 

and see which dirs pop up.  On my system, dirs include
/usr/share/fonts/default/Type1, /usr/share/fonts/afms/adobe, etc...
They you can set your AFMPATH to point to these dirs.

You don't need to set the DPI for a postscript file since postscript
is scalable.  The DPI is determined by your output device, eg, a
1200x1200 DPI printer.  This parameter is ignored by matplotlib on the
PS backend.

Good luck,
