It looks like you're missing some prerequisites for running Apache::Session. From a quick look, it appears that you'll need Storable, MIME::Base64, and MD5 to run anything, and some others for the more specific Session::* modules (i.e. DBI for Apache::Session::DBI).
Since Session appears to do a terrible job of checking for prereqs, here's a list of everything it appears to need, ever:
[/var/tmp/.cpan/build/Apache-Session-1.53] $ find -type f | xargs tcgr
+ep -e '^use [A-Z](?!.*Session)' * |perl -pe's/[^:]+://' | sort | uniq
use Fcntl qw(:flock);
use IPC::SysV qw(IPC_CREAT S_IRWXU SEM_UNDO);
use Storable qw(nfreeze thaw);
And hmm, can I use "post here, read here" on PM?
