portmanager and perl handling

[Noah]

I am running portmanager with the following switches "portmanager -u -f 
-l -y"
 which is building all the dependencies.  I find that perl is set to the 
system version of 5.003 .   I do not want this behavior.

I want to keep updating Perl to the newer version and I want perl to 
always be set to the latest port which is currently 5.8.8.  what do I 
need to change in my portmanager.conf file to make sure this happens?

Cheers,

Noah
