cperl-mode has perldoc access, just look under the Perl->Perl Docs menu
for the keyboart shortcut.  I generally don't use it, personally,
because from the command line I can do zsh completion (e.g. 
"perldoc -f <TAB>" will show a completion list of all the documented
functions and "perldof List::<TAB>" will show all the available List::*
modules).
