conda build fails

[nikohansen]

When I try to create a conda build from the current master branch (unfortunately, in tag r3.3.0 the settings of tools/conda.recipe/meta.yaml are not up to date) on macOS ARM

conda-build -q tools/conda.recipe 

I get this error

[...]/opt/anaconda3/lib/python3.9/site-packages/conda_build/environ.py", line 801, in get_install_actions
    raise DependencyNeedsBuildingError(exc, subdir=subdir)
conda_build.exceptions.DependencyNeedsBuildingError: Unsatisfiable dependencies for platform osx-arm64: {'numpy=1.16'}

@matt-chan any idea how I can address this problem?

[matt-chan]

I'm not entirely sure, sorry. M1 builds are a bit dicey because not all reps have been built afaik. Also, are you intending to build with conda-forge dependencies?

Also, I don't have an M1 Mac to reproduce with right now unfortunately.
