Only the actual shared libraries are required to be installed, and they are imported directly by path via ctypes. The package's patchPhase already takes care of embedding the Nix store paths of the required libraries into pyopengl. This reduces the transitive closure size of PyOpenGL: 622M -> 136M.

PyOpenGL is the cross platform Python binding to OpenGL and

related APIs. The binding is created using the standard (in

Python 2.5) ctypes library, and is provided under an extremely

liberal BSD-style Open-Source license.
