Have you looked at CGI::Fast ? It permits persistence like mod_perl, but is easier to set up and configure. I've just begun playing with it myself for caching the DB hash for a Perl-based online game, but it's doing well so far. For you, CGI::Fast should allow you to keep the dictionary in memory between invocations. Another technique I've used is to run the C program as a daemon process, and then connect to it through a socket from your perl program when you need to do operations. But that's probably overkill for your case...
