Synced then trying to update world results in:

!!! The following update has been skipped due to unsatisfied dependencies:

net-print/hplip:0

emerge: there are no ebuilds to satisfy ">=dev-python/imaging-1.1.7-r2[python_targets_python2_6(-)?,python_targets_python2_7(-)?,python_single_target_python2_6(+)?,python_single_target_python2_7(+)?]".
(dependency required by "net-print/hplip-3.12.11-r1" [ebuild])

I checked dev-python/imaging. Looks like the latest version in funtoo portage is 1.1.7-r1 and hplip needs imaging-1.1.7-r2.
