[rt-devel] cgi error from support.pm

[Michael A. Walter]

Hello -

Today I found a bug in support.pm - or at least my Linux system was not
happy with it.  :)

I installed the tar.gz file and rt ran great, then I got a checkout of
the cvs tree (v. 1.0.7) and ran into a problem.

#
# The problem is that neither of the cgi exe's work.  When executing
# them from the command line, I get the following output

Looks like the importing url code is causing problems.  If it helps, I'm
running RH 6.2, and Apache 1.3.2.

Let me know if you need any more info,
