I am trying to install the latest Boost.Python code on a freshly installed Mac OS 10.2 with the Jun or Jul developer's kit + Aug patch. With a very minor fix compilation of the core library goes smoothly, but my first attempt at linking libbpl.dylib failed miserably. See attached log. I'd be grateful if any of the Apple experts out there could help figuring out what is wrong.
