lresources.ppu is found, but rejected. It seems to be an old file, maybe from a previous release.
Let me think ...
Maybe you should edit the Lazarus directory in the Environment -> Path options, so that is uses the current Lazarus directory.
Please find other occurrences of lresources.ppu and set the lazarus directory to three directories above. So for /Applications/Lazarus.app/lcl/units/powerpc-darwin/lresources.ppu -> /Applications/Lazarus.app.
If you delete (or for safety reasons) rename /usr/local/share/lazarus to /usr/local/share/lazarus.to.be.removed, then Lazarus probably will complain about a missing Lazarus directory.
