That wouldn't work in this case.  The script is a daemon (postfix policy 
service), not a user program.

The best I've come up with so far is to install the script to 
${PREFIX}/share/${PORTNAME}, then add a note to pkg-message to have the 
user copy the script to runnable location (i.e., the postfix config 
directory), edit the internal config and set the path in /etc/rc.conf. 
This means a manual step to install/upgrade and an orphan when the port 
is deinstalled, but it's the least-evil solution I've come up with.
