Installation documentation: what are the dependencies for compiling arbtt?

[Gwern Branwen]

An acquaintance wanted to use --dump-samples but her arbtt was too old
(apparently the Ubuntu package is well behind the times?) and so
installed a fresh one from Hackage when a compile error hit:

    cabal: Error: some packages failed to install:
    X11-1.6.1.2 failed during the configure step. The exception was:
    ExitFailure 1

As many Xmonad users know, this is the common problem of having not
installed the headers/-dev package for the X11 library, which then
makes the X11 Haskell bindings impossible to compile, which makes
arbtt impossible to compile:
http://www.haskell.org/haskellwiki/Xmonad/Frequently_asked_questions#Missing_X11_headers

The solution is to install libx11-dev on Debian or xorg-dev (which
isn't mentioned in http://arbtt.nomeata.de/#install ).

But are there any other foreign dependencies which need to be
mentioned for people installing from source?
