Dos2unix requirement/python versus python3 on mac

[sophiakolak]

Not sure if this is a personal problem, but if I run python venv on my mac it tries to use Python2 instead of Python3, which causes the compilation to fail with "No module named venv". Changing to python3 fixed this for me. It still fails with "dos2unix: command not found" which I fixed by separately installing dos2unix. I'm not sure about the python/python3 thing, but it seems like dos2unix should either be listed as a requirement or handled in the script. I noticed there is a block that originally checked for the installation but it has been commented out and I wasn't sure why
