Summary: compile error with graphs/minimal example?

Initial Comment:
I'm trying to compile a PyX program (first time). I have one based on 
graphs/minimal:

#!/usr/bin/env python
from pyx import *

g = graph.graphxy(width=8)
g.plot(graph.data.file("historical-fp-performance.dat", x=1, y=2))
g.writeEPSfile("historical-fp-performance")

after running "python setup.py install" (I did enable the kpathsea 
build as well). This is on python 2.3.5 on OS X 10.4.1. I have tried 
this with both PyX 0.7.1 as well as the CVS version (trace below is 
for the CVS version). 

Error trace follows, then an error trace from "make" in the manual 
directory. Help?

Thanks for the debugging output. The fontmapping files are
ok, the
problem was in PyX's parsing code. I've just checked in the
trivial fix.

Sure thing. Attached.
The entries in the map file are ones that are generated from the otftotfm 
tool in the LCDF TypeTools. If there are problems with how that tool 
generates map files, we should track that down (the author is good with 
updates when necessary).

(I'm sorry for the late response. I'm right back from vacation. Could you 
please stick on the 0.7.1 release for our further discussion. The CVS is 
known to be partially broken (although I don't expect your problem to be 
related to that) and its easier to watch for tracebacks on released versions, 
where we can easily reproduce all line numbers in files and tracebacks 
etc.)

The problem you encounter seems to be related to our parsing routine of 
your "psfonts.map". I'm wondering for what case our parser emits a 
NoneType in the token list. Could you please insert a debugging print 
statement at the top of the constructor of the fontmapping class. At 
release 0.7.1 insert a line "print s" at line 499 in the file. Also add a "print 
tokens" right after the 517 and run your test again. You should be able to 
reproduce the problem already at the most simple TeX-using example, 
which is hello.py in the example directory.
