I'm really clueless about the whole configure/automake system.  I tried to
use it once for one of my own projects and it really didn't simplify the
process any.  I just endup up pulling out hair and going to handcrafted
build scripts.

Configure.ac (and all its macros) read to me like Greek (and no, I don't
know Greek).

Is XCursor a separate package?  SDL requires it but having all the SDL
devs installed does not make this file present anywhere on my system.
When I need to look for a file I use:

find / -name "<file-being-looked-for>" 2>/dev/null
(the redirect of stderr is becuase find / looks in things like devnodes
and /var which includes a lot of things that find won't be able to stat)

Hence:
cowboy at ...56...:~> find / -name XCursor.h 2>/dev/null
cowboy at ...56...:~>

Indicates the abosulte abscence of this file anywhere on my system.
