'sifflet' requires cairo ==0.11.0 and pango.
Indeed.
But since pango doesn't work with cairo 0.11.0, the package can't be built.
Uh... it seemed to build just fine for me (when I did it all manually). I'm not sure I see what the problem is here. I made Cabal install 0.11.0 of each package, by hand, one at a time, and it never complained of any unfulfilled dependencies, and the end result was a runnable program. So I'm just puzzled why it couldn't figure out that you can do that by itself.
Those specific versions of packages are overly constrained. They should follow the PVP, and be thus,
0.11.*
Yeah, that seems to be the root of the problem.
