how can we use those from MacPorts? Is it possible?

Either use macports to downgrade to an older version of the cairo C lib, or grab the darcs version of gtk2hs and try that. If macports only supports has one version of a lib at once (I seem to recall someone saying that's the case) then you'll have to pick the second option. Duncan

Installing gtk2hs from MacPorts on a clean mac:

svgcairo/Graphics/Rendering/Cairo/SVG.chs:201:2: Couldn't match expected type `()' against inferred type `CInt'

The latest major release of the cairo C lib changed the API to return an int status code for a C function that previously returned void.

c2hs guarantees us some degree of cross-language type safety and caught this api change for us (by turning it into a Haskell type error).

I expect the updates to work with the new cairo api are in the gtk2hs darcs version.
