libxcb needs to find the python package in the path specified by pythondir
recorded in xcb-proto.pc. If the libdir line is deleted, libxcb will report an
error when compiling:
| Failed to load the xcbgen Python package!
| Make sure that xcb/proto installed it on your Python path.
| If not, you will need to create a .pth file or define $PYTHONPATH
| to extend the path.
| Refer to the README file in xcb/proto for more info.
The file contents after deleting libdir are compared as follows:
