I am not sure, but there may be a problem with CGI::Session. When I did a query on it, it said to contact the author. When I tried to install it through CPAN, I got this:
cpan> install CGI::Session
Running install for module CGI::Session
The module CGI::Session isn't available on CPAN.
Either the module has not yet been uploaded to CPAN, or it is
temporary unavailable. Please contact the author to find out
more about the status. Try 'i CGI::Session'.
You may want to contact the modules author.
