Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Looks like a OS X build of protobuf 3.0.0 is needed before this can be build. Also note that the default protobuf is being installed in Linux.

Hi! This is the friendly automated conda-forge-linting service.

I was trying to look for recipes to lint for you, but it appears we have a merge conflict.
Please try to merge or rebase with the base branch to resolve this conflict.

Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.

Looks like 32b6244 was caused by some wonky setup on my laptop. I am not seeing any issue rerendering the feedstock on my main development machine.

Can someone review this PR before merging?
