OK, "./configure --help" outputs the following:
--includedir=DIR        C header files in DIR [PREFIX/include]

I've tried adding --includedir=/usr to configure and that results in the same 
error message.
I've also tried adding --includedir=/usr/include and that too has no effect.

Am I missing something obvious ?

(I've also just re-built my kernel to verify that the necessary kernel header 
files are in fact present on my system)
