Description
Hello, thanks for creating vips and providing excellent documentation.
When i do pip install pyvips on my Mac running OS Catalina I get the following errors. I have vips version vips-8.10.4 which I installed with homebrew. I'm able to install version 2.0.5 with pip and the conda installation works likely since it comes with the prebuilt binary.
