Yeah, that's mentioned as a small side note in the blog post - we are working on...

OK got there in the end! I didn't time it but felt like around 10 minutes or more.

It did give me one warning message:

That sounds like the compilation is accidentally triggering this old frustration [0].

Compilation was slow for me on macOS too.

We'll improve this very soon, right now the experience is less than ideal.

Ideally we would download the compiled artifacts instead of compiling as Simon commented... it will be a much better experience for everyone!
