A purpose of UPDATING file is to give users a short note about changes
in a port that may affect them.
You can get details how ports work by reading Hendbook and Porter's
Handbook. For certain ported software you will direct to the software
documentation.

A port may depend on other port(s). When the port installs, the ports
system checks if dependencies are installed. If they are not installed,
they will be installed before.
Let's look on www/mod_perl as an example. It depends on a few ports.
apache is one of them. Decision if apache installed or not takes by
checking PREFIX/sbin/apxs file (Porter's Handbook describes how
dependencies are defined). If the file does not exist, www/apache13 port
will be installed.
But if you have already www/apache13-modssl port installed,
PREFIX/sbin/apxs will be in a place and dependency will be satisfied.
There is no difference for the ports system between www/apache13 and
www/apache13-modssl as a dependency.
portupgrade rely only on information from port dependencies list (you
can see it e.g. with 'make run-depends-list' from a port directory). And
it knows nothing about www/apache13-modssl can be used instead of
www/apache13. So it should be described in pkgtools.conf file as an
example bellow.

OK. For -nox11 suffix you should define something like this:
MAKE_ARGS = {
'*-nox11*' => 'WITHOUT_X11=yes',
}
It should be work, but I did not test it. If I'll get a report that it
works, I'll able to add this example.
