Comment (by jamestwebber@…):

 I'm having the exact problem that meowsqueak reports: bjam hanged after
   {{{darwin.link.dll bin/darwin-4.2.1/debug/extending.so}}}
 But I can run test_extending.py fine after killing the command and export
 the relevant variables. No new wrinkles from what's been previously
 reported, but wanted to add another data point.

 I'm using OS X 10.7.5 and python 2.7.3 built with homebrew, boost 1.50.0
 and bjam built locally from boost.

 Digging a bit into the commands, I can see as dave did that Python is
 running, with the command
 {{{
 "/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/bin/python"
 "test_extending.py"   >
 "bin/test_ext.test/darwin-4.2.1/debug/test_ext.output" 2>&1
 }}}

 But when I run that command alone (after compiling) it runs fine. The
 test_ext.output looks fine except that it starts with the characters
 `\E[?1034h `which appears to be related to some weird behavior from
 readline (CAPTCHA isn't working so I can't post this link, but: search for
 "readline+1034h")? I have no idea if that might cause a problem--I'm not
 sure how it would.

 If I kill the Python process it remains hanging, but killing the bash
 script stops the test (which then fails because the output is wrong).

 == Actually... ==

 I tried running the testing script manually, by pasting this into the
 terminal:
 {{{

 /bin/sh -c
 DYLD_LIBRARY_PATH="/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib:/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config:/usr/local/boost_1_51_0/bin.v2/libs/python/build/darwin-4.2.1/debug:/usr/local/boost_1_51_0/libs/python/example/quickstart/bin/darwin-4.2.1/debug:$DYLD_LIBRARY_PATH"
 export DYLD_LIBRARY_PATH

     PYTHONPATH="bin/darwin-4.2.1/debug"
 export PYTHONPATH
 "/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/bin/python"
 "test_extending.py"   >
 "bin/test_ext.test/darwin-4.2.1/debug/test_ext.output" 2>&1
     status=$?
     echo >> "bin/test_ext.test/darwin-4.2.1/debug/test_ext.output"
     echo EXIT STATUS: $status >>
 "bin/test_ext.test/darwin-4.2.1/debug/test_ext.output"
     if test $status -eq 0 ; then
         cp "bin/test_ext.test/darwin-4.2.1/debug/test_ext.output"
 "bin/test_ext.test/darwin-4.2.1/debug/test_ext"
     fi
     verbose=1
     if test $status -ne 0 ; then
         verbose=1
     fi
     if test $verbose -eq 1 ; then
         echo ====== BEGIN OUTPUT ======
         cat "bin/test_ext.test/darwin-4.2.1/debug/test_ext.output"
         echo ====== END OUTPUT ======
     fi
     exit $status
 }}}

 The result is that my terminal hangs--I have to close the window and open
 a new one. It does successfully run the tests, though, and outputs the
 results.

 If I omit the last line (`exit $status`), it runs fine and doesn't hang.
 So perhaps this is happening because the shell script is exiting out of
 the user's bash shell, never returning control to bjam? This doesn't
 explain why I didn't see the test.output file before, I guess. And I would
 guess that the exit status is good to know. But this might be the cause of
 the problem.
