	Right ! and that sucks. So - I wonder, could we make the error message
more helpful in this failure case:

	"You don't have doxygen, please either install it or pass;
	 --without-doxygen [or similar]. Disabling it will not
	 impact your build, unless it is a product build"

	If we are too difficult for newbies to build, this is a big problem,
and not one to take lightly.

	Of course, we don't want to accidentally break distro packages by
adapting to an incomplete system either.

	Potentially we could auto-fit to the system more aggressively to help
newbies, but fail aggressively on missing packages if some
--enable-product (or whatever) option is passed. Perhaps that might
capture the best of both worlds (?).

	ATB,

		Michael.
