[Haskell-cafe] Problem with GTK on OS X -- installed from source

Building my app with gtk2hs, I get the following error when I try to compile a file that uses Template Haskell (I'm not using TH to do anythign with GTK, but it loads the package anyway) Loading package gtk-0.9.13 ... <command line>: can't load .so/.DLL for: gthread-2.0 (dlopen(libgthread-2.0.dylib, 10): image not found)
