Is the location of the test page
http://fetishfiends.com/test.shtml ? If so, I just tried it and I am not getting the same source code as you posted!
Also where is the Perl script? I have tried both
http://fetishfiends.com/cgi-bin/readblog.cgi and
http://fetishfiends.com/cgi/readblog.cgi both of which go to what I assume is your 404 page, which infers the script does not exist at either location.
