The best thing to do is to convince the guys running RELENG_4 to join the rest
of us in the 21st century, and switch to 8.0 or at least 7.x. Support for the
4.x base system has ended some time ago, and the current ports tree isn't
guaranteed to work on it either.

Create a virtual machine with RELENG_4 on it, that is probably the most
foolproof way. (If you are running an i386 machine, maybe a jail will work.)
Try to compile the software on it. If that software is in ports
and the current port doesn't compile or run, either roll back your ports tree
to a version that works, or try to patch the port to make it work.

Ditto.
