app-office/akonadi-server-1.6.2 links against the largest installed slot of dev-libs/boost, ignoring the version selected by "eselect boost". Reproducible: Always Steps to Reproduce: 1. emerge dev-libs/boost:1.46 dev-libs/boost:1.47 2. eselect boost set boost-1.46/default 3. emerge app-office/akonadi-server 4. ldd /usr/bin/akonadi_agent_launcher | grep boost Actual Results: libboost_program_options-mt-1_47.so.1.47.0 => /usr/lib64/libboost_program_options-mt-1_47.so.1.47.0 (0x00007ffbc4c5c000) Expected Results: libboost_program_options-mt-1_46.so.1.46.1 => /usr/lib64/libboost_program_options-mt-1_46.so.1.46.1 (0x00007ffbc4c5c000) Noticed this when upgrading the slot of boost I use for development from 1.47 to 1.48 and I had to rebuild akonadi-server.
