kdnssd and zeroconf-ioslave blocking each other (Solved)

[Featherfoot]

When I upgraded my KDE system to 4.12.4, I got a message about kdnssd and zeroconf-ioslave blocking each other. I deleted zeroconf-ioslave on he assumption that this would resolve itself. A couple of weeks have gone by and the problem still is there. I wonder if anybody has thoughts on how to fix it.

Here is the blockage:

For more information about Blocked Packages, please refer to the following
section of the Gentoo Linux x86 Handbook (architecture is irrelevant):

I have repeatedly tried unmasking both packages to see if new versions would fix the problem. So far this hasn't happened.

kde-base/zeroconf-ioslave replaces kde-base/kdnssd in kde-base/kdenetwork-meta-4.12.4.

[TomWij]

When there is a blocker, it has been set by the developer because the packages (or the specific versions thereof) are not known to work together; in this case removal of one of both is necessary, sometimes an upgrade or downgrade to a version that doesn't have this blocker is possible. For the latter, you can look into the ebuilds in the package's directory to see which one specify the blocker; blockers can be found in the DEPEND, RDEPEND and/or PDEPEND variables, they have a ! or !! in front of the package ATOM syntax.

The problem was that kdenetwork-meta was set for version 4.11.4 rather than 4.12.4. It is working now.

Thank you for your help!
