Installation problems on Darwin ARM system

Executing the setup script from a Mac M1 (Darwin arm64) I basically run into 4 problems listed below. Miniforge and gcc-12 was installed beforehand via brew.

Problem 1

./setup.sh: line 37: [: =~: binary operator expected
./setup.sh: line 39: [: =~: binary operator expected

EnvironmentNameNotFound: Could not find conda environment: scilabrl
You can list all discoverable environments with `conda info --envs`.

HINT: On OS X, install GCC 9.x with `brew install gcc@9`. or `port install gcc9`.

Problem 3 and 4 are probably related.
