Is it possibly to detect which OpenSSL is used for a port?

[Naram Qashat]

This isn't quite what I'm looking for. I want to be able to tell within a
port's Makefile if the user wanted the base or ports OpenSSL to be used.
I've been trying to port TDE to FreeBSD, and tdelibs uses pkg-config to
check for OpenSSL. This would work if the only form of OpenSSL was in
ports, but the base OpenSSL doesn't have a pkg-config file to use, so I
need to know which is going to be used so I can determine when this
pkg-config check can be removed.
