[gentoo-user] ps2pdf /undefinedfilename but only when run from perl

I have a project which uses a perl program to run the ps2pdf command.
It fails when run by the perl program but works fine when run by me
from the command line.  No environment variables are changed -- the
perl program is pretty harmless.  This is really frustrating -- I can
literally print the proposed command from the perl program, copy and
paste it into the same shell window, and it runs fine, no errors and
the ps is converted to pdf nicely.

Here is the complaint from ps2pdf:

    /usr/bin/ps2pdf13 /tmp/print-32248.ps /tmp/print-32248.pdf
    Error: /undefinedfilename in (/tmp/print-32248.ps)
    Operand stack:

    Execution stack:

    Dictionary stack:

    Last OS error: 2
    ESP Ghostscript 815.01: Unrecoverable error, exit code 1

I have been working on this on and off on several systems, only one of
which is gentoo.  It has generally been the same on all systems,
except for the gtk libs on this machine (rPath) being sufficiently out
of date that firefox 2 beta 4 won't run.  But this has nothing to do
with firefox.

Google shows that the most common cause of this error is spaces in
file names.  But this name has none, and even removing thedash doesn't
change it.

I am going to start simplifying the perl wrapper, but that's a slow
tweaky road.  Does anyone have experience with this error from ps2pdf?
