Sorry to hear this got so complicated, this doesn’t sound like this was fun – or how it is supposed to go.
This sounds like it was using the system compiler, but for some reason that wasn’t picking up shared libraries correctly. Not sure why this would have happened however.
Hopefully at some point in the not-so-distant future we will be able to get rid of the C backend (which is usually the culprit of issues like this) and switch to the numba backend. This should completely solve issues like this one.
