This is ugly hack. The header does not need to be in the standard path
at all. What you should do instead is to call
AC_SUBST([KEYUTIL_LIBS, ...) in the configure part and do
LDLIBS+=$(KEYUTILS_LIBS) here. Have a look at the m4/ltp-acl.m4 or
m4/ltp-cap.m4 for instance.

What do we create the temporary directory for? The test does not seem to
work with files at all.

                                            ^

				Technically it didn't fail, but only
				stub was compiled due to missing
				library.

It should say something as:

	"keyutils.h was missing at compilation"
