Problem: When I try to install app-pda/libopensync-plugin-kdepim-0.20 (marked unstable) without having kdepim installed first, the subject whon't compile and stops with a compile error. Sugestion: There should be a check in the ebuild that makes kdepim a dpendency if it is not installed.
DEPEND="=app-pda/libopensync-${PV}* || ( kde-base/libkcal kde-base/kdepim )"
