Boost-Build :

On darwin, "gcc-4.0 -arch ppc64" seems to be all that is needed -- I
also had to pass "-arch ppc64" to the linker as well. I managed to
build boost-1-33-1 this way and have used it for some 64-bit
projects, but some modules failed to build completely. In particular
the testing framework didn't build (or maybe it just failed to link,
I can't remember).

Do I also need e.g., some other defines, to let the preprocessor know
that this is being built in 64-bit mode (so that e.g., macros for 64-
bit clean-ness get turned on)?

If it would be helpful I can come back with more detailed info about
the problems I ran into, if anyone could help me debug it.
