Not in scope: type constructor or class `CUInt'

I have made a package for getting and installing Gtk2HS from darcs (gtk2hs-darcs), on Arch Linux. Someone is reporting to me this:

And I responded him with:
I think I may know what is going on, but I just can't believe no developer of gtk2hs is having gstreamer, and a 32 bits system. ;-) gtk2hs is using c2hs, to make a .hs file from .chs, by consulting C headers files. gstreamer/Media/Streaming/GStreamer/Core/GObjectHierarchy.chs choose to import only CULong, because on the author system (which must have 64 bits), this is what the C file header return. But because you have 32 bits (correct me if I am wrong), your C header file return a 32 bit value, so CUInt must be imported too. So you would have to make a new clean install, but stop the system after darcs got src installed. Then edit in gstreamer/Media/Streaming/GStreamer/Core/GObjectHierarchy.chs to remove '(CULong)' on the following line: import Foreign.C.Types (CULong) that way, it will import all the types, CUInt included. Or just make it '(CULong,CUInt)'. I am new to Arch, new to Haskell, and new to Gtk2HS, so I may be out of track however.
Not sure I am Ok, and a developer could verify if there is other files like this. The package can be found http://aur.archlinux.org/packages.php?do_Details=1&ID=14976&O=0&L=0&C=0&K=gtk2hs&SB=n&SO=a&PP=25&do_MyPackages=0&do_Orphans=0&SeB=nd
