Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: gi-cairo-connector-0.1.0 (user goal)
[__1] next goal: gi-cairo-render (dependency of gi-cairo-connector)
[__1] rejecting: gi-cairo-render-0.1.0 (conflict: pkg-config package
cairo-gobject==1.13 || >1.13, not found in the pkg-config database)
[__1] rejecting: gi-cairo-render-0.0.1 (conflict: gi-cairo-connector =>
gi-cairo-render==0.1.*)
[__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
