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.

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.

Great, PyPy37 and Python3.10, both of which worked on the 3.4.3 testing builds and the 3.5.0 main builds are failing. Twice now.

@QuLogic I had to revert matplotlib/matplotlib#21277 (the combination of matplotlib/matplotlib#21263 and matplotlib/matplotlib#21279) to get matplotlib 3.5.0 to build freetype 2.6.1 on Linux on both Python 3.10 and PyPy3.7. Otherwise, we get an error:

I'd need to see config.log for details.
