security/gnupg2 MESSAGE needed? (or fix)

[coypu%SDF.ORG@localhost]

Hi, to generate key with this successfully I needed to write:
 pinentry-program /usr/pkg/bin/pinentry
in ~/.gnupg/gpg-agent.conf

Without this, it was failing to generate a key.
It may be good to write this in MESSAGE, if it cannot be made to respect
PATH.
