[gentoo-user] udisks wants to downgrade udev and parted - but why?

[Helmut Jarausch]

Hi,

I'm puzzled again by portage's logic.

When trying to emerge sys-fs/udisks-1.0.2-r4
it wants to downgrade sys-fs/udev from 171 to 168-r2  and
sys-block/parted from 3.0 to 2.4

The udisks' ebuild contains
>=sys-fs/udev-147[extras]
>=sys-block/parted-1.8.8[device-mapper]

sys-fs/udev hasn't an 'extra' use flag and
sys-block/parted-3.0 has been emerged with the device-mapper
use flag.

But why does portage try to downgrade these to packages?

Thanks for shedding some light on this one,
Helmut.
