Bill, Your glibc version installed is too old to use the binary distribution I provide. Your WS3 is several years old, so likely the gcc/glibc environment has not been updated to a recent version such as the version the binary distribution is compiled with under Fedora 4.0. You can either compile the distribution yourself from source, or upgrade your glibc/gcc environment.
