No, it’s a Homebrew thing. The system libxml2 doesn’t have a .pc file,
so they created their own one to point to it. Unfortunately when Apple
stopped shipping the includes that setup stopped working.

IIRC, if you look in the directory you’ll see other .pc files for
other system libraries. Libxml2 just seems to be the one that causes a
lot of hassle.
