Error: 'Module' object has no attribute 'global_variables'

I upgrade to the latest numba (0.17.0) using macports on mac osx 10.10.02 and now I cannot compile any numba functions anymore. Compilation fails with the following error:

The same setup worked with numba version 0.16. Let me know if you need further information about my setup.

This looks like llvmlite needs updating. Running conda update llvmlite should resolve the issue.

Well, the problem was actually that I needed to downgrade llvmlite. My macports already installed llvmlite 0.3.0, which is apparently incompatible with numba 0.17.0 (which is also installed via macports). One could argue that this is a problem with macports, but on the other hand a more useful error message on numbas site would also help. Anyhow, I now have a running numba installation again.

We haven't officially released llvmlite 0.3.0 (although it is tagged, so I can see how the macports package maintainer might have assumed it was released), which contains a method name change that requires a corresponding change in numba.
