The port only installs php.ini-dist and php.ini-recommended, which are the
ones from the PHP source tree. If neither of these is copied to php.ini then
php.ini-dist is hardcoded inside php itself, also not something the FreeBSD
port alters.

As expected.
However, stuff in /etc/profile applies to all Bourne type shells.

Correct. You can however clean the entire environment, by setting
apache22limits_enable="YES" and apache22limits_args="-e -E -C daemon".
If you need specific variables to be available and the rest to be gone, the
standard rc script doesn't support it. You'd have to roll your own.

For portability yes, since it doesn't rely on EGPCS, but otherwise they give
the same results.

Problem with today's modular software: they start with the modules
and never get to the software part.
