Before shouting (or comparing to rpm-4.5 behavior), you need some additional information.

Meanwhile you have reported a LOOP message (and you have already seen that the
_dependency_whiteout macro changes/simplifies rpm behavior).

rpm-5.x has additional dependency rules:

	1) every file "requires" its parent directory
	2) every symlink "requires" its target end-point

I put the "requires" in quote solely because yoi will _NOT_ see this
information with
	rpm -qp --requires foo*.rpm
queries. Otherwise the additional "requires" behave exactly like
other Requires:, both as dependency assertions and as pre-requsites
for topologically sorting.
