The only problem is that pushing all of this logic into bsd.*.mk only
solves half the problem: from source installations. It doesn't cover
binary installations via pkg_install.

I think Doug and Phillip were on the right track with pushing the data
into a pkg_install consumable format, but the only problem is that
creating additional code that handles one more corner case for
@comment will serve to only slow down the plist parser unnecessarily.
That's why I was suggesting a scripting infrastructure, like so:

pkgmsg() {
    local message=$1
    echo "$message"


echo "This is an install message for my awesome new package
foo-<BLAH>" > +DISPLAY
pkgmsg `cat +DISPLAY`

And considering that you almost get the functionality for free via
pkg_install (from pkg_create(8)):

     -D displayfile
             Display the file (by concatenating it to stdout) after installing
             the package.  Useful for things like legal notices on almost-free
             software, etc.

The thing about using a script function like pkgmsg too is that it can
be dynamically overwritten by certain groups in order to tailor the
messages (or mute output for customer purposes after everything has
passed QA if they use pkg_install in a product) to the meet their
needs when doing localized installations or deployments as well.

So, why not just add the relevant bits as I described?
