You'd get better results asking on jlime's forum, but anyway, only the base modules were installed. The individual perl modules are seperate packages as not everyone needs every module and it saves space. Look at
http://repository.jlime.com/hp7xx/mongo/feed/base/ and install the modules as needed. Or if you have no idea what includes 'comm' install them all. It is full perl after all, just broken down in many packages.
Cheers.
