Thanks John, it certainly does help. I'm building the Boost libs for 
MacOSX. I get release and debug variants, but none of the libraries 
contain the "-mt" in their names. I did convince myself that 
BOOST_HAS_THREADS was defined for every file that was compiled, so now 
I'm satisfied that I really do have multi-thread libraries. There does 
seem to be some bug in the build, though, because the library file names 
indicate that they are single-threaded.

Thanks again,
Rush
