There isn't anything wrong with having multiple compilers installed on
a given system, insomuch as they install within separate directories
or are prefixed differently. The sym-/hard-links for the compiler last
installed may be the one that gets used though (not sure because I
don't have any experience installing gcc from ports on FreeBSD)...

This ties into the reply above, but if you have a compiler provided by
the base system and a compiler provided by ports, they won't install
in the same location, as ${PREFIX} dictates in ports.
