As this thread already made clear, there are good reasons why you might want to run 32-bit apps as well as 64-bit apps on your 64-bit hardware. So the 32-bit libraries live in /usr/lib and the 64-bit ones in /usr/lib64. If you ask me, the really serious mistake in this design is they didn't decree separate bin directories /usr/bin and /usr/bin64 too. This makes it impossible to install 32-bit and 64-bit versions of the same package at the same time, something that curiously enough people are now demanding support for. (Personally, if I'd designed it, the libraries would actually live in /usr/lib32 and /usr/lib64, and /usr/lib would be a symlink to whichever you needed it to be at the moment. Likewise for /usr/bin.) regards, tom lane
