I don't believe some web hosts. They use Perl 5.003. Ok, stable version, nice. But... no CGI.pm??? It's Perl on a web server for cryin' out loud!
CGI::Simple proved to be the perfect solution. It required 5.004 and used "for my $varname (LIST)" in-loop-declarations, but that was easily fixed so I could use it in the limited environment. Just upload the module, edit the script in two places and * poof * it works!
