MacPorts operates under the assumption that exactly one port will

Sometimes this occurs because perl5.8 didn't used to include a
particular module (hence a separate port was created) but now due
to a version update perl5.8 does already include that module
(making the separate port unnecessary). Sometimes the separate
port may provide a newer version.
Ok, so if I am getting this, perl5.8 has a module already installed
and the p5 I want to put is in also trying to put it in. This is
the core conflict?
I believe that is correct, yes.
Which one do you chose is the issue?
There are a few p5 ports that print messages advising users to force
the activation of the p5 port. This would cause the p5 port's module
to overwrite the perl5.8 port's module. The assumption is that the p5
port provides a newer version.
At the very least, let me chose, but the -f can force things to
happen even deeper down the chain, and it would be a bear to back
out of those.
I do not think we need to change the MacPorts error message from
the one that is currently being printed. It is accurate.
I agree, though we need to figure out how to make the message go away.
There is a ticket for this problem, I believe it has been mentioned
earlier. I believe the possible fixes are 1) delete the p5 port for
which a module is already included in the perl5.8 port; 2) delete the
module from the perl5.8 port so that the p5 port can provide it; 3)
integrate the p5 port's module into the perl5.8 port in the event
that it is newer; 4) make the p5 ports install modules into a
separate location from where the perl5.8 port installs modules (the
question then is how to make perl-using software see both sets of
modules; I am not a perl expert so I do not know the answer).
