You'll get this error if the "Python.h" header file you built PyMOL with is different from the one corresponding to the Python library you're using. The message is usually harmless. PyMOL will seem slow unless you have a hardware graphics accelerator, with suitable drivers (under Linux). PyMOL does not perform at all well using software OpenGL (Mesa) because it does not use display lists. - Warren
