UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support Problem running ubb6_test.cgi

Here's the scoop: I get an Internal Server Error #500 when I try to run it. I got the hello.pl and hello.cgi scripts to both run, but the test won't even run. When I ran the file through a script checker (provided by AITcom) I was rewarded with the following:

TEST 4: perl syntax
Can't locate strict.pm in @INC (@INC contains: /usr/lib/perl5/i686-linux/5.00404 /usr/lib/perl5 /usr/lib/perl5/site_perl/i686-linux /usr/lib/perl5/site_perl .) at ubb6_test.cgi line 55.
BEGIN failed--compilation aborted at ubb6_test.cgi line 55.

I have an extremely limited knowledge of CGI, and this is my first venture using a lot of it, so any help would be very much appreciated!

BTW, the script is stored here: http://www.bettendorfstanford.com/cgi-bin/ubb/ubb6_test.cgi
