portmanager and use.perl port

[Noah]

Hi,

So at times I run portmanager on many of my servers but I want to make 
sure that the perl installed is the port and not the system version.

The only option I new about was to IGNORE building it.

# grep perl /usr/local/etc/portmanager/pm-020.conf
IGNORE|lang/perl*|

But I am wondering if there are proper settings that I can put in placed 
to make sure that if perl is reinstalled that the port version is the 
chosen version.

Cheers,

Noah
