Yes, we have challenges ahead of us sorting this out. For an example, here’s a
little tiny Portfile that is supposed to install SageMath. It’s a prime
candidate for a “cask” port, and does a fine job of exhibiting the problems to
be faced.
Put it in a folder called “binary/sagemath-binary” to see it work, if you like:
