While I was debugging a perl script and installing various cpan modules I noticed I had both perl5.8 and 5.9 installed.  Both were marked as active but perl5.8 was linked to /opt/local/bin/perl.  I decided to deactivate perl5.8 , deactivate perl5.9 and then reactivate perl5.9.  After doing so the /opt/local/bin/perl link is gone so it doesn't link to to perl5.9 (as I would expect). 

Is this a bug?

It's a feature, Perl 5.9 is a "development" release... Maybe the port should have been called "perl5.9-devel" instead, to make this more self-explanatory perhaps ? --anders
