Support latest homebrew gcc
Describe the bug According to https://github.com/openai/mujoco-py/blob/master/mujoco_py/builder.py#L311 only gcc versions 6-8 are support on macOS. Now the latest version of gcc on homebrew is 9, which means that the install process is broken by default and the recommended fix:
brew install gcc
no longer works.
To Reproduce Install homebrew gcc@9 and then attempt to install mujoco-py.
Expected behavior
mujoco-py to work with gcc@9.

The same error.
But downgrade of gcc to v.8 was helpful for me.
brew install gcc@8
Issue still exists with gcc@9 and on macOS 10.15 I am unable to use gcc@8 too.
For those who don't want to pin homebrew gcc to an older version for some reason, try setting the CC environment variable. It will override the automatic gcc detection logic (which supports up to gcc-8).
export CC=/usr/local/bin/gcc-11 # assuming you have gcc@11 installed with homebrew
pip install mujoco-py
With this building wheel for mujoco-py should work. I don't think you should downgrade your gcc.
@wookayin This did not work for me. It still shows the same error. Uninstalled the already existing mujoco-py, before re-installing. Anything that I'm missing?
