just some explanations ;-)

For information about prelink see "man prelink" and your configuration file /etc/sysconfig/prelink.

rpm -V takes care of the prelink issue. You can remove the changes done by prelink with

# prelink -u /usr/bin/md5sum

Afterwards /usr/bin/md5sum should be identically to /usr/bin/md5sum in the rpm package. md5sum belongs to 
coreutils. Unpack the coreutils rpm in /tmp:

# cd /tmp
# rpm2cpio coreutils-5.97-12.1.el5.i386.rpm | cpio -iudv

and compare /tmp/usr/bin/md5sum with /usr/bin/md5sum.
