Greetings,

My issue seems to be the same as in this old thread: http://lists.boost.org/boost-build/2008/02/18486.php
but that thread does not describe a solution.

I can build boost.python without errors using both the "darwin" and "clang" toolsets, 
but I cannot build the second quickstart example located in
libs/python/example/quickstart/extending.cpp (using either toolset).

When I run:

$ cd libs/python/example/quickstart/
$ ../../../../b2 -a toolset=clang --verbose-test test

The first quick start example builds and runs successfully, but the second one never finishes building.
The boost.build output hangs at this line:

clang-darwin.link.dll bin/clang-darwin-4.2.1/debug/extending.so

I would be grateful for any assistance you can provide.

Thanks in advance,
Stuart
