Thanks for looking into this, much appreciated!

Oliver, would you mind clarifying why 'multi-lib' needs to be built?  I
assume you're referring to the threading=multi, and by the way we haven't
been using that when building the other boost binaries for our project.

I think I figured out the problem, Boost.Context seems to require
"address-model=64" to be in the b2 command, regardless of my settings in
user-config.jam.  Adding that and everything, including Boost.Log, built
fine.

For the records, this is how I'm building Boost.Log universal binaries for
Max OS X 10.8.3:

// in user-config.jam:

using clang : osx
: xcrun clang -arch i386 -arch x86_64 -stdlib=libc++ -std=c++11
;

./boostrap.sh --with-libraries=log

./b2 -a -d+2 -q toolset=clang-osx link=static address-model=64 stage

cheers,

Rich
