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?

    (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.

    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).

    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.
