Found that gtk was not installed. So I did
  brew install gtk

but I got different problem

Hi,

I'm new to cabal/stack. I want to use "stack build" to build my project.

I can not use latest gkt >= 0.14.2 because of
   setup: The pkg-config package 'cairo' version >=1.2.0 is required but it could

Neither can I now use older version gtk >=0.12.0 && < 0.13

While constructing the BuildPlan the following exceptions were encountered:

--  Failure when adding dependencies:    

      gtk: needed (>=0.12.0 && <0.13), 0.14.2 found (latest version available)

    needed for package: ships-0.1.0.0



What can i do? Thanks
