nixpkgs/pkgs/development/python-modules/cairocffi/dlopen-paths.patch
Dima 7ff2638b7f pythonPackages.cairocffi: v1.0.2 -> v.1.1.0
The tests were failing due the switch to pytest5.
This issue has been addressed upstream in
a500f20866
which is included in v.1.1.0, so bumping the version and
updating the old patch.
