Yes I figured that out on my own but my question still exists, why isn't /usr/lib similar in format to /usr/lib32 though with respect to major numbers? Actually now that I re-read your paragraph I suppose this isn't such a bad idea but for some reason I believe that if you have /usr/lib before /usr/lib32 it should *just* work. -aps
