This is a side effect of prelink (do a "man prelink"), which modifies binaries to make them faster. To verify that your files are okay, try rpm -V -v tcsh Or you could also do something like, host1$ prelink -y /bin/tcsh >/bin/tcsh.orig host1$ md5sum /bin/tcsh.orig host2$ prelink -y /bin/tcsh >/bin/tcsh.orig host2$ md5sum /bin/tcsh.orig -- Deron Meranda
