RE: Changes to make fptools insfrastructure usable for standalone libraries

Hi Alastair,

I've fixed some of the problems with your X11 package now, hope you
don't mind.  Installation might still not quite work - you might need to
add the --force argument to ghc-pkg to avoid it complaining about the
libraries not existing yet.  Apart from that, it seems to build cleanly.

The package still depends on "lang", which might cause problems: we
don't currently have any hierarchical packages which depend on
non-hierarchical packages; for some reason this makes me uneasy but I
can't quite put my finger on why.

It should be possible to do this, but I haven't tried.

Yes, this is another case of the fptools build system not being very
modular.  Maybe it'll get cleaned up one day.
