After testing it out on your system, it seems to be that "make
install" fails if using EIGEN2 and the Python bindings (this is
already reported at
http://sourceforge.net/tracker/?func=detail&aid=3399341&group_id=40728&atid=428742).
I need to fix this.
If not using Eigen2, then it all works fine for me with the system
python (python2.6) and swig:
cmake ../trunk -DCMAKE_INSTALL_PREFIX=`pwd`/../install
-DPYTHON_BINDINGS=ON -DEIGEN2_INCLUDE_DIR= -DRUN_SWIG=ON
After make && make install, I defined
LD_LIBRARY_PATH=`pwd`/install/lib and
PYTHONPATH=`pwd`/install/lib/python2.6/site-packages, then "import
pybel" worked fine.
