Installing CGI::Session on Apache 2.0.46

I am trying to get CGI::Session to work, specifically for running
Twiki. However, I get this error from Twiki's configuration page:

You can use persistent CGI session tracking even if you are not using
login. This allows you to have persistent session variables - for
example, skins. Client sessions are not required for logins to work,
but TWiki will not be able to remember users unless there is some
other mechanism - such as browser cacheing of authentication -
available. # See TWiki.TWikiUserAuthentication for a full discussion
of the pros and cons of using persistent sessions.
Error: The CGI::Session Perl module is required for session support,
but is not available.


These are the relevant packages:

httpd-2.0.46-57.ent
mod_perl-1.99_09-10.ent

And the Perl-related configuration section on httpd.conf

<FilesMatch "(attach|edit|manage|rename|save|upload|view|.*aut h).*">
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
PerlSendHeader On
PerlOptions +ParseHeaders
</FilesMatch>


I have installed CGI::Session through CPAN:

cpan[1]> install CGI::Session
CPAN: Storable loaded ok
Going to read /root/.cpan/Metadata
Database was generated on Tue, 20 Feb 2007 14:09:29 GMT
CGI::Session is up to date (4.20).


cpan[2]>



What could be missing?


Many thanks,

Hmm... that should not be the case. I wrote a CGI script to show the
@INC path:

#!/usr/bin/perl

print "Content-type: text/html\n\n";

print "\@INC is @INC\n";


Here's the output:

@INC is /usr/lib64/perl5/5.8.0/x86_64-linux-thread-multi /usr/lib/
perl5/5.8.0 /usr/lib64/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl/
5.8.0 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.0/
x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/
perl5/vendor_perl /usr/lib/perl5/5.8.0 .

CGI::Session should be installed:

$ locate Session|grep -i cgi
/usr/lib/perl5/site_perl/5.8.0/CGI/Session/Tutorial.pm
/usr/lib/perl5/site_perl/5.8.0/CGI/Session/ErrorHandler.pm
/usr/lib/perl5/site_perl/5.8.0/CGI/Session/Serialize
/usr/lib/perl5/site_perl/5.8.0/CGI/Session/Serialize/json.pm
/usr/lib/perl5/site_perl/5.8.0/CGI/Session/Serialize/storable.pm
/usr/lib/perl5/site_perl/5.8.0/CGI/Session/Serialize/freezethaw.pm
/usr/lib/perl5/site_perl/5.8.0/CGI/Session/Serialize/yaml.pm
/usr/lib/perl5/site_perl/5.8.0/CGI/Session/Serialize/default.pm



Is there a way for a CGI script to show what Perl modules are
available?


Thank you,
