Just to double-check: You built on Linux, copied the binaries to macOS and were 
able to execute them? Because as far as I understand, releases are not built 
natively right now...

Not sure what you mean by "good", ie if python -V doesn't crash and prints 
3.7.4 I would be happy for now. A small functional test might be
 $ <...>/python3 -c "import time; print(time.time_ns())"
which is a new function added in Python 3.7 (I guess this won't be used in 
LilyPond, but that would be a way of making sure that it's indeed running the 
python libraries from GUB and not loading some other modules, like from the OS).

I had changes laying around to build a version of LilyPond ported to Python 3, 
let me see if I can clean them up and get them into another branch for people 
to test...

Cheers,
Jonas
