Cool C libraries we could have on hackage server

Hi, I just submitted bindings to libusb, and realized I should comment pkgconfig-depends in .cabal since libusb-1.0 is not installed on the server, or cabal would refuse building it. There are many libraries we probably would like to have bindings for, but we need to have them on hackage to do that. What if we generate a wish list of really trusted and important libraries we would like to use, and then test if they build on hackage, and install in /usr/local those that do? I have a few sugestions: http://www.gnu.org/software/gsl http://www.hdfgroup.org/HDF5 http://libusb.sourceforge.net http://sourceware.org/libffi http://directory.fsf.org/project/mailutils Best, Maurício
