I have installed the most recent versions of Forge and the mods I am trying to use (buildcraft and divine rpg), but Minecraft crashes while trying to load (after the Mojang screen). 

It says "java.lang.IllegalArgumentException: Slot 4095 is already occupied by buildcraft.energy.BlockOilStill@6c21f22f when adding xolova.blued00r.divinerpg.blocks.BlockXolovonStone@28a3231f."  Is there anything I could do to fix this problem?

 

 

Here's the crash report:
