Rebuilding perl with threads

[Toomas Aas]

Hello!

I'm in a process of installing a new server. I have already built and  
installed a lot of ports over the past weeks, and now that I'm almost  
done I discovered that one of the last things I need to install  
(misc/amanda-server) needs Perl installed with threads support,  
whereas I have it installed without threads.

For this kind of change, is it safe to reinstall just the Perl port,  
or do I also need to rebuild all ports that depend on Perl? That would  
be a *lot* of rebuilding. The version I currently have installed is  
perl-5.12.2_2, lang/perl5.12 seems to currently be at 5.12_4.
