[LON-CAPA-admin] Dynamic Plots on Debian

I've really been poking in the guts of this thing now, and probably know
more than I ever wanted to about how dynamic plots work. This is what
I've found out:
as root, if I:
gnuplot /home/httpd/perl/tmp/file_plot.data > test.gif
I get a gif that both xv and mozilla can view without a problem.
If I artificially set the QUERY_STRING environment variable to
so I can run the plot.gif script and pipe the output to test.gif,
both mozilla and xv spit up on it.
The Content-type seems to be the culprit to my unprofessional eye.
Perhaps something with my version of apache?
I've got apache 1.3.26-0, and lib-apache-modperl 1.26-3.0 from the stable
One last datapoint: I just tried viewing a dynamic plot page with IE, and
it doesn't seem to like it either.
Hope that helps some.
