Installing PERL modules from CPAN (instead of ports)

[Sahil Tandon]

In order to setup postfwd (http://postfwd.org), of which there is no FreeBSD 
port, several PERL modules are required; one of them, Net::DNS::Async, also 
does not exist as a FreeBSD port.  If I install this via CPAN, postfwd works, 
but then this breaks portupgrade and portmanager when trying to update perl 
or keep track of new versions of the bsdpan-* "packages".  Is there another 
way to go about this outside of trying to create my own postfwd and 
Net::DNS::Async ports?
