I am using OpenGL to render a scene in python. My code works perfectly fine on windows but, for some reason, I'm having issues when importing opengl.gl on MacOS.

The issue arises when calling `from OpenGL.GL import ...` in both python scripts and the python console.

More specifically here is the exact call in my script:

```
from OpenGL.GL import glGenBuffers, glBindBuffer, glBufferData, \
    glGenVertexArrays, glBindVertexArray, glEnableVertexAttribArray, glVertexAttribPointer, \
    glDrawArrays, glUseProgram, glEnable, glDisable, \
    GL_ARRAY_BUFFER, GL_STATIC_DRAW, GL_DEPTH_TEST, \
    GL_FLOAT, GL_FALSE, \
    GL_TRIANGLES, GL_LINES, GL_LINE_STRIP

```

This results in the following error:

```
       Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/OpenGL/platform/darwin.py", line 35, in GL
    return ctypesloader.loadLibrary(
  File "/usr/local/lib/python3.8/site-packages/OpenGL/platform/ctypesloader.py", line 36, in loadLibrary
    return _loadLibraryWindows(dllType, name, mode)

    return dllType( name, mode )

    self._handle = _dlopen(self._name, mode)
OSError: ('dlopen(OpenGL, 10): image not found', 'OpenGL', None)

During handling of the above exception, another exception occurred:

**Notes**:

* Running glxgears works just fine.
* I'm running macOS Big Sur beta (20A5343i)
* I'm using python 3.8.5
* I installed opengl using pip: `pip3 install PyOpenGL PyOpenGL_accelerate`
