Warning: The install command is a part of the legacy v1 style of cabal usage.
Please switch to using either the new project style and the new-install
command or the legacy v1-install alias as new-style projects will become the
default in the next version of cabal-install. Please file a bug if you cannot
replicate a working v1- use case with the new-style commands.

cabal: Could not resolve dependencies:
[__0] trying: gi-cairo-connector-0.0.1 (user goal)
[__1] next goal: gi-cairo-render (dependency of gi-cairo-connector)
[__1] rejecting: gi-cairo-render-0.0.1 (conflict: pkg-config package
cairo-gobject>=1.13, not found in the pkg-config database)
[__1] fail (backjumping, conflict set: gi-cairo-connector, gi-cairo-render)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: gi-cairo-connector, gi-cairo-render
