The ports tree is just there for installation from source and putting 
the software after compile into canonical locations (and adding 
usually the necessary startup scripts etc. in the process - Ports are 
not to be mixed with packages.

As FreeBSD supports the source centric way from centralised location, 
there shouldn't really be any need for doing the compile outside the 
ports tree. You can basically tweak the ports to your hearts content 
(most of the relevant options can be tweaked from the ports Makefile 
already) and in addition the port installs into location using a 
method the rest of FreeBSD users can give you meaningful advice.
