RTFM install issue

I installed RT recently and tried to install RTFM as well. RTFM built just
fine and placed the RTFM directory inside /opt/rt3/share/html however no RTFM
link shows up when any user logs in even root. if I goto
http://rt.domain.com/RTFM I get the following. Can anyone point me in the
right direction here?
thanks

“RT::FM::ArticleCollection” (perhaps you forgot to load
“RT::FM::ArticleCollection”?)
