I'm upgrading from Python 2.6.5 to 2.7.1, and I'm getting the error below when compiling my code using Boost 1.45 and gcc 4.2.1 in OSX 10.6.6.  The following thread describes similar symptoms related to the ordering of header files and macro definitions:
http://code.google.com/p/unladen-swallow/issues/detail?id=87#c13

The suggested patch to pyport.h (http://codereview.appspot.com/179049/patch/1/2) does not fix my problem.  However, prepending 

#include "Python.h"

to each source file (e.g., bend.cc below) does fix the problem.  Is there a simple way to fix this without adding Python.h to every source file in my codebase?

I've installed Boost and Python from source to non-standard directories, Boost 1.45 by:
cd $(BOOST); ./bootstrap.sh --prefix=$(CURDIR)/$(BOOST) --with-python-root=$(CURDIR)/$(PYTHON_DIR) --with-python-version=2.7 --with-libraries=mpi

and Python 2.7 by:
cd $(PYTHON_SRCDIR) ; ./configure --enable-shared --prefix=$(CURDIR)/$(PYTHON_DIR)
cd $(PYTHON_SRCDIR) ; make -j $(NUMPROC) && make install

Any guidance will be greatly appreciated.

Kind regards,
Nasos
