error when building blender as python module

Hi,
I’ve been trying to build blender as a python module based on the description here
http://wiki.blender.org/index.php/User:Ideasman42/BlenderAsPyModule
and here
http://wiki.blender.org/index.php/Dev:Doc/Building_Blender/Mac

Unfortunately, make install files after changing the CMAKE options.
I’m running this on a mac, os x 10.7, Xcode 4.2, python 3.3 is installed.
The last few lines of output are as follows:

Linking CXX shared module …/…/bin/bpy.so
Undefined symbols for architecture x86_64:
“_GHOST_user_locale”, referenced from:
_bl_locale_set in libbf_intern_locale.a(boost_locale_wrapper.cpp.o)
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
make[2]: *** [bin/bpy.so] Error 1
make[1]: *** [source/creator/CMakeFiles/blender.dir/all] Error 2
make: *** [all] Error 2

Any idea what I need to change? Thanks!
