I use the java parts of lang/gcc3.  (I've actually been working on getting
boehm-gc working with pth to make this possible under 1.6.x.)  And Fortran
*is* used by some parts of pkgsrc, so you probaby should include it.

FUD, to be sure, but....

Huh?

So make a "pkgtools/gcc3" stripped down version of it, and let

You haven't even tried using "--with-languages" yet, have you?  (Hint:
Only setting the LANGUAGES env var at "configure" time works properly at
"make" time; this is a known gcc bug.  8-)

Building the Java bits requires building the C and C++ bits in full, so a
"full gcc3" package *will* conflict with a "non-java gcc3" package.
Again, how about a "pkgtools/gcc3"  for the stripped down version and leave
the full version to work as gcc3 "normally" builds?

As an alternative:  Make a Makefile variable such as GCC3_EXTRA_LANGUAGES
that defaults to empty and can be changed in mk.conf to modify what
languages are built for the pkg.  This would be added to the list "c c++
f77" that is put into LANGUAGES when building gcc3.  And since gcc3 already
uses dynamic PLIST generation, you have no problem in creating a proper
PLIST for the requested languages.
