The file in question defines a foreign imported IO action of arity 14,
but nhc98 can only cope up to arity 12 at present.

I would guess it is 'gluUnProject4'.

Have a look in src/prelude/Internal/Internal.hs where _mkIOok[0..12]
are defined.  Just for you, I have now checked in functions up to
arity 15.  (Don't forget to 'make prelude' again, or you will get
link errors.)
