[rt-users] Need "DB_PORT" in Makefile and support throughout build

[Darrin Walton]

  |+ This might seem a silly question, but why?

Some of us run multiple database servers on the same machine for various
reasons.  Testing a new version of a database, testing software (you
wouldn't want to be doing testing on the production database), etc.

While many of you may say 'why not put it on another machine'.  This is
not always possible.
