Seems like it hasn't correctly linked against OpenGL. But it ought to give that error at build time, not run time. Make sure it's using the wheel you built and not some other one. I do fortunately have a RPI3 so I can test it... but it works fine for me. Maybe ask on Raylib Discord.

I do recall that Raylib has issues with Pi support, and I think only works on certain versions of Raspbian because Raspbian keeps changing how the OpenGL drivers work.

Thanks for the reply. Doing a clean build of my pi and moving to Buster. Will report back and close/update this soon. I did notice that my python was not able to use the wheel and ran the setup.py, so I'll make sure I have wheel support working first.

I'm closing this as I worked around it, but I could not get this working. I did a clean install with Buster on raspian lite, installed dependencies, built raylib, got pkg-config working (that seemed more difficult than expected), and raylib installed, and pip installs fine, but it gave cffi errors whenever I try to run. I then installed raylib_dynamic and it works just fine, so I'm going with it. I do think complete steps on a pi would be useful to document, but maybe it just isn't that common to do what I'm doing. Thanks again for the reply.

We did actually have some tutorial for Pi in the docs, written by the last person who got it working. But Pi changed and those steps didn’t work any more! I don’t have time right now, especially since it works for me, but when/if I do I will try a from scratch install and see if I can reproduce.
sometimes people on the discord have more free time, still might be worth asking there.

Everything should now work on RPI3 (and 4 I presume) Bullseye with Raylib X11 (PLATFORM_DESKTOP) and with Raylib PLATFORM_DRM.
Older OSes and Raylib PLATFORM_RPI probably wont work.
See https://github.com/electronstudio/raylib-python-cffi/blob/master/RPI.rst
Please reopen if not working.
