I would say set PREFIX to install the port in a non-default location.

With Xorg every gui app wants to use the X libs so I think setting
LD_LIBRARY_PATH could get around that, but I would keep the old version
in /usr/local and install the new version elsewhere until you get it
running.

See chapter 9.4 PREFIX and DESTDIR of porters handbook for more info.
