PS and PDF backends silently fail / give bad output (diagrams 0.4) on os x lion

Looks like a Cairo bug, can you test its PDF generation from another program?

I had a similar problem with ps/pdf generation when trying out the Chart library (again png output would work). In the case of Chart, the compiled haskell programs would outright crash / have a memory allocation issue on the C lib side.

Does that help clarify?

Apparently there's an incompatibility (or possibly bug) with lion's preinstalled version of cairo, which was built with llvm:

https://trac.macports.org/ticket/30370
Homebrew/legacy-homebrew#9518

I fixed this issue (as recommended in the homebrew ticket) using

brew install cairo --use-clang

Then I reinstalled gtk2hs using

cabal install cairo gtk --extra-include-dirs=/usr/local/Cellar/cairo/1.10.2/include --extra-lib-dirs=/usr/local/Cellar/cairo/1.10.2/lib --reinstall

After running those steps, pdf and ps output work fine for me.

Closing now, since it's clear it wasn't a diagrams bug and it seems like a solution/workaround has been figured out, see https://gist.github.com/1655271

I'll also add a link to the above solution on the wiki.
