- Move Perl's man1 files along with its man3 files.
- Move where Perl installs its modules man1 pages.
- Convert the ports installing man1 pages.
- Make different Perl versions installable at the same time.
Though you should note that only the default version can be used to
install Perl modules, and the non default Perl versions cannot use the
modules installed via ports if they contain .so as they are installed
in a version specific directory.
