What I've tried:

- Removed "export MANPATH=/opt/local/share/man:$MANPATH" from .profile.

- Added to /etc/manpaths.d/:
   $ cat /etc/manpaths.d/macports
   /opt/local/share/man

- Ran path_helper:
   $ sudo /usr/libexec/path_helper -s
PATH="/opt/local/bin:/opt/local/sbin:/usr/local/bin:/Applications:/usr/ 
bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin"; export PATH
MANPATH="/opt/local/share/man:/usr/share/man:/usr/local/share/man:/usr/X11/share/man 
"; export MANPATH

- Opened new terminal:
   $ man perl | grep 'perl v5.'
   perl v5.8.8                        
2006-01-07                           PERL(1)

- I also tried adding the path to /etc/manpaths:
   $ cat /etc/manpaths
   /opt/local/share/man
   /usr/share/man
   /usr/local/share/man

It didn't change the result. Apple's man page [for perl items] still  
takes precedence. Any ideas? I wonder if this has anything to do with  
the man#p dir that the macports perl man page is stored in? "opt/local/ 
share/man/man{1,3}p"

Checking the manpages for other items installed by macports reveals  
that this isn't global. It appears to be related only to the perl  
pages noted above. Example:

] port installed | grep autoconf
   autoconf @2.64_0 (active)
] man autoconf | grep "GNU Auto"
GNU Autoconf 2.64                  July 2009                        
AUTOCONF(1)

That displays the manpage from macports and not Apple's autoconf man  
page.
