The current version of GCC in brew for macOS is gcc-13, but install-deps.sh
explicitly exports CC=gcc-11 in install_osx(), which is not found and causes
the swig configure to fail.

Unfortunately, I think you need to list all the versions of gcc that brew has
installed and pick the latest one. 

Here's a diff of the change that worked for me:
