This is going to be a can of worms for you to automate, here are a few 
reasons why:

What if apache2 is all ready installed without SSL turned on?
What if the user wants other features besides SSL?

Suggestion:  Test for a library that will only exist if apache2 has
been installed with WITH_SSL_MODULES=yes and if that library is missing
then have your port refuse to build with a message that apache2 must be 
built with WITH_SSL_MODULES=yes.

If you are using autotools (automake/autoconf) you can place this sort 
of a test in configure.ac.
