I am using Boost.Python under OS 10.3.2 with Xcode v1.1 all the time, but I
don't do embedding and I use a SCons-based build system. I'd guess that your
problems are related to differences in the build system, or more specifically
the compilation commands that are issued by the build system. Even more
specifically, it looks like
"-I/System/Library/Frameworks/Python.framework/Versions/2.3/include/python2.3"
is missing. Which build system are you using? Could you post the command line
that leads to the "no such file" errors? If you are using bjam, add "-d2" to
the bjam command line to see the commands that are issued.
