Eternal lands depends on =cal3d-0.10.0 crystalspace (dependency of planeshift) required =cal3d-0.11.0_pre* If possible, both versions should be allowed installed, otherwise cal3d is in up/downgrade loop if both are installed.
Unfortunately I can't slot cal3d. I added blockers between the versions to prevent the endless up/downgrade loop and alert users about the problem. Thanks for your bugreport.
