When emerge kmess-1.3 and kde-3.3.1 some of the code found previously in the kdenetwork ebuild has been moved to the kdepim ebuild, so kdepim has to be installed to get it to compile. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Please report this to the developers of kmess. We're maintaining ebuilds, fix bugs, but cannot develop the applications, too.
There's no new version of kmess for 14 months now, so if there doesn't happen anything upstream, it'll be removed from portage in a while.
