I'm trying to build the recently-added-to-trunk Boost.Log on OS X and smacking into an error when it includes unsupported.cpp. I've google'd around a bit and seen from the macports guys that Boost.Context doesn't currently build for 32-bit architecture, but I can't even get it to build for just 64-bit. Has anyone had success yet with Boost.Log on OS X, or has some insight into how to get this working before it makes it into 1.54?
