As I said, for people who don't have the experience with the
compiler toolchain, it could be safer to use a "build from source
packaging environment" like pkgsrc or gentoo-arch.
The can be configured to the OSABI to be used and build all
packages against this ABI.

I know that pkgsrc is supporting MacOS X 10.6 in 32-bit mode, too,
because some of our pkgsrc committers have target (not build) machines
running 32-bit only and they build 32-bit packages to their requirements
on 64-bit osx hosts.

Sorry for repeating this again - but I think using such a pkg system
would be the best way for questions like OP.
