/mnt/lustre/home/maciek/openbabel/openbabel-svn/scripts/python/openbabel-python.cpp:20526:
undefined reference to `OpenBabel::OBFreeGridPoint::OBFreeGridPoint()'
CMakeFiles/bindings_python.dir/python/openbabel-python.cpp.o: In function
`_wrap_delete_OBFreeGridPoint':
/mnt/lustre/home/maciek/openbabel/openbabel-svn/scripts/python/openbabel-python.cpp:20557:
undefined reference to `OpenBabel::OBFreeGridPoint::~OBFreeGridPoint()'
collect2: ld returned 1 exit status
