Some of these packages are currently slotted with the previous 2.x release, breaking programs that depend on the old versions. For example, regexxer depends on gconfmm-2.0.1. But gconfmm-2.6.1 installs *-2.6.* files (eg gconfmm-2.6.pc), which regexxer (looking for *-2.0.*) can't find. Reproducible: Always Steps to Reproduce: 1. emerge dev-cpp/gconfmm-2.0.1 2. emerge dev-util/regexxer-0.6, it builds and runs 3. do an upgrade to unstable (emerge dev-cpp/gconfmm-2.6.1) 4. regexxer can't find libgconfmm-2.0.so.1 Expected Results: There should be gconfmm-2.0.2 (the latest 2.0.x) and gconfmm-2.6.1 ebuilds, slotted differently (Perhaps SLOT="2.6" as in bmg). This probably applies to other gtkmm/gnomemm ebuilds. I haven't check all of them.
Thanks for the report, this was my fault, fixed now.
