5507	Template Haskell needs extra library dirs	jwlato	igloo	"Template Haskell fails to link c libraries which are located in non-standard locations.  On my system, gtk libraries are installed in /opt/local/lib; ghc-pkg describe reports:

{{{
library-dirs: /Users/kathleenhouse/.cabal/lib/cairo-0.12.1/ghc-7.2.1
              /opt/local/lib
}}}

and building ordinary Haskell packages with cairo/gtk works properly.

However, if a package imports Cairo, Template Haskell fails to find the C library.  The error (from ghc) is:

{{{
Loading package cairo-0.12.1 ... <command line>: can't load .so/.DLL for: libcairo.dylib (dlopen(libcairo.dylib, 9): image not found)
