Good catch Waitman.  And thanks for sharing an approach to avoid GPLv3
inclusion. 

Though you've raised an interesting question as to whether the licencing
information displayed by "pkg info" is accurate where a port pulls in
mandatory dependencies that use a more restrictive open source licence.

Of the subset of ports that I use (servers only), the ports [licences]
that may be of concern are:  python27 [PSFL], mediawiki [GPLv2],
mysql56-server [from mysql web GPL], pcre [BSD3CLAUSE] also use readline
and aren't tagged as GPLv3 which they probably should as FreeBSD
metaports requires readline?
