Apple's current c++ (based on gcc 3.1) doesn't work. I am using g++ 3.3
compiled from sources. How about renaming the toolset to darwin-gcc-tools.jam?

-Wall creates a lot of noise for my compilations, but we could still try it for
the Boost.Python regression tests.

The -DBOOST_PYTHON_MAX_BASES=2 is an attempt to cut down our compile-times. I
think it should be omitted from the bjam toolset. The -DBOOST_PYTHON_SOURCE is
already set somewhere by bjam (?).

I obtain the -I path by looking at sys.executable and sys.version in Python.
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/cctbx/libtbx/libtbx/config.py?rev=1.5&content-type=text/vnd.viewcvs-markup
I am not sure how this could fit into the bjam framework.

Sorry, I don't understand what you mean here.

I am not entirely sure I understand your question. Trial answer: I only could
get it to work when specifying the full path. My experiments with
-L/Library/Frameworks/.../2.3 failed. Maybe because Python doesn't exist with a
.dylib extension?

You are right, -bundle doesn't take a value. But the full
/Library/.../2.3/Python path has to appear somewhere. Maybe this is most
logical:

g++ -w -bundle -bundle_loader
/Library/Frameworks/Python.framework/Versions/2.3/
Python -o libtbx/scitbx_boost/rational_ext.so
scitbx/boost_python/rational_ext.o
s -Llibtbx -L/net/cci/rwgk/boost_releases/1_30_0/mac/libtbx
-lscitbx_boost_pytho
n -lboost_python /Library/Frameworks/Python.framework/Versions/2.3/Python -lm

This didn't work for me with the Python 2.3b1 installation.

If you modify the toolset and check it in I will try it out. I don't think
there is a reason to be conservative since the old one never worked for
compiling and linking all Boost.Python regression tests AFAIK, due to bugs and
limitations of compilers older than gcc 3.3.
