The problem is caused by the hwdb useflag, though I had to read the udev
ebuild file to understand the error message :-/
RDEPEND="${COMMON_DEPEND}
hwdb?
(
>=sys-apps/usbutils-0.82
sys-apps/pciutils[-zlib] <<<<<<<<<<<<<< look here
)
That syntax means "if you want hwdb support in udev you must disable zlib
for pciutils". I have no idea why the two are incompatible, but it sounds
to me like "an implementation detail" thingy.
In any case, if you need -zlib in one package and zlib in another you can
set/unset the needed flag for just one package in /etc/portage/package.use.
