Closes (hopefully) #78

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.

@isuruf, this is still using clang-12 for osx-arm, which is the same that was used to build the previous build:

    clang:                         12.0.1-h694c41f_4         conda-forge
    clang-12:                      12.0.1-default_he082bbe_4 conda-forge

Issue was clang-12 was used, but it was a bad build.

I also cannot find any clang 12 builds that were marked broken since #77...?
