To upgrade from 5.6.x to 5.8.x (with no 5.8.x installed):
'portupgrade -o lang/perl5.8 lang/perl'

As mentioned previously, be sure to follow the directions in 
/usr/ports/UPDATING.  You may need to change the upgrade command 
slightly to reflect you're coming from 5.6.x instead of an earlier 
version of 5.8.x (change the 5.8.2 to 5.6.1 as below):

portupgrade -f `(pkg_info -R perl-5.8.4 |tail +4; \
   find /usr/local/lib/perl5/site_perl/5.6.1 -type f -print0 \
     | xargs -0 pkg_which -fv | sed -e '/: ?/d' -e 's/.*: //')|sort -u`

After rebuilding everything, you may want to finalize the upgrade by 
cleaning out /usr/local/lib/perl5/ and /usr/local/lib/perl5/site_perl. 
Due to incorrect plists, there may be some files left there from 5.6.x. 
  It might be a good idea to check that each file is present in the 
5.8.x directory before deleting (as a sanity check for the upgrade), but 
after the complete rebuild it should be safe to remove everything.  The 
goal is to completely get rid of the 5.6.x directories:

$ ls /usr/local/lib/perl5/
5.8.4           site_perl
$ ls /usr/local/lib/perl5/site_perl/
5.8.4

I've not had any problems with this method (used on many machines 
running 4.10, 5.2.1, and -CURRENT), but it's best practice to have a 
full backup before the upgrade as it touches on a huge chunk of the 
system...
