This is another reason autotools has worked so well for us. You can build
most anything by simply running:

  prompt> configure.sh
  prompt> gmake
  prompt> gmake install

Pretty standard. If you want to build against a different version of a 
dependent library (the latest-greatest is found automatically if not otherwise
specified) by doing:

  prompt> configure.sh --with-<some lib>=<non-default version>

The defaults "do the right thing" for the guy who just wants to build a 
release, yet the overrides allow an expert to make custom builds.

Our build system also directly supports the notion of development vs.
production builds, so that a developer can build a developement release and
test on his/her local system without disturbing production applications.
