Basically there is a way, BUT last time I tried it with gcc3, I got as far as
building C compiler, when building C++ compiler the configure script would go
into an infinite loop.

I think it would be better to build gcc4 instead, I've done it on Solaris 10
and managed to build C, C++, Objective-C, Fortran and Ada compilers. gcc4
automatically includes support for building 32-bit and 64-bit binaries.

I think gcc4 is not in pkgsrc yet, but I believe John Shannon is working on
porting gcc4. He has a beta lang/gcc4 package on his website (search pkgsrc
mailing list to find out web address). I think at some point that package needs
to be split up into lang/gcc-c, lang/gcc-c++, lang/gcc-ada, etc packages, so
that you could build pure C compiler with minimum dependancies, and then use
that compiler to build everything else (well except for ada, which needs a
bootstrap ada compiler)
