My apologies for not writing to you about it sooner. The problem is that
maxima determines the location of its supporting files based on where it
was installed initially, where the executable is now, and the value of
the environment variables MAXIMA_PREFIX (or the deprecated version,
MAXIMA_DIRECTORY.) The environment variable takes precedence. TeXmacs,
for some reason, sets MAXIMA_DIRECTORY to null. Maxima then assumed that
it was installed in "/", which caused it to not find the plotting
program. I added a check to see if MAXIMA_DIRECTORY was empty. If so,
Maxima now ignores it. It would be better if TeXmacs didn't set
MAXIMA_DIRECTORY.
