Hi Baris,
To install bindings for python2 and python3 simultaneously, I had to make
some edits to CMakeLists.txt, which can be seen at
https://github.com/openbabel/openbabel/pull/33
After making those edits, I was able to do the below on my mac (10.8):
#build for python2.7
cmake -DRUN_SWIG=ON -DPYTHON_BINDINGS=ON ..
make -j12 && make install
#delete cmake cache, build for python3.3
rm CMakeCache.txt
cmake -DRUN_SWIG=ON -DPYTHON_BINDINGS=ON
-DPYTHON_EXECUTABLE=/usr/local/bin/python3.3
-DPYTHON_LIBRARY=/Library/Frameworks/Python.framework/Versions/3.3/lib/libpython3.3.dylib
-DPYTHON_INCLUDE_DIR=/Library/Frameworks/Python.framework/Versions/3.3/Headers
..
make -j12 && make install
#test 2.7 and 3.3 packages, should not show any import errors
PYTHONPATH=/usr/local/lib/python2.7/site-packages/ /usr/bin/python -c
'import pybel'
PYTHONPATH=/usr/local/lib/python3.3/site-packages/ /usr/local/bin/python3.3
-c 'import pybel'
