Libreoffice perl dependency

[James Griffin]

pkg_add -r libreoffice pulls in perl5.14 but all my ports have been built against perl5.16 so i'm wondering if this will cause a problem, i.e. having two perl versions installed. The installer did setup new symlinks in /usr/bin to the older version of perl, which I can easily change but I just want to check before going forward if and what I should change to avoid problems. 

Cheers, Jamie.
