I've opened #3724 to reproduce this problem.

The issue appears to be that py3cairo is using Python 3 to run python3.6-config, which is a shell script, so it complains about invalid syntax. Which means your solution makes a lot of sense 😄

Would you like to open a PR to add that environment variable to the formula? Getting it right for all users might be a little tricky, but we can help you out with it along the way. If not, no worries 😄
