Among others, this way, users do not have to modify their PATH (and
other settings) which as you noted is necessary with the approach you
described for your GNAT port.

It's not.  I've carefully ensured, by means of proper configuration
options and several bug reports and pushes upstream, that all our
recent lang/gcc ports (gcc33, gcc34, gcc40, gcc41, and gcc42) install
conflict free, with the exception of gcc41 and gcc42 if Java is used.

Yes, GNAT should install into ${PREFIX}/bin as well, using the
--program-suffix= option, like the lang/gcc ports are doing.

Depens which ports you have in mind. ;-)  It's probably not worth in
terms of disk space and build time to do this for the regular lang/gcc
ports.  These already are quite complex, plus by installing one of these
without C++, for example, you'd cause problems for other ports using 
this one as a build dependency.
