Below is the code in mpl that actually does the lookup. To get to the
bottom of this, I would try to figure out in your Apache/PHP environment
what
a) what os.path.expanduser("~") gives
b) what the values of the environment variables "HOME", "USERPROFILE",
"USER", and "TMP" are.
I suspect either matplotlib is not getting run under user 'apache' as it
should, or there is something fishy about the environment.
Cheers,
Mike
