Sure, you can make all calls to hat-trans and ghc directly yourself, but
that is rather cumbersome. You cannot use anything like ghc --make,
because ghc doesn't know about Hat.

hmake uses its own little database of compilers. You can tell hmake
about the compiler through
hmake-config add ghc
hmake-config default ghc
http://www.haskell.org/hmake/hmake-config.html gives more details.

This indicates that you will run into a more serious problem. Hat
currently only supports a limited set of libraries and Graphics.X11.Xlib
is not among them.
If an unsupported library is just a normal Haskell module, a simple
solution is to copy it into the same directory as your own code (modify
the module name accordingly) and just treat it as part of your program.
However, this soon becomes more complicated if the library requires
further modules and special link options.
