I gave this advice for recovery before and may well work for you.
What I suggested;

You can force updates and installs 

->rpm -Uvh --force --nodeps filename.rpm

If that doesn't work  move each into a clean directory
(I.E. mkdir 1 etc.), then;

->rpm2cpio libbeecrypt6-4.1.2-9.1_10.rhfc4.at.i386.rpm | cpio -iv 
--make-directories .  #note '.' for current dir.

->mv -f  file /to/the/proper/dir 
# the rpm2cpio will make subdirectories in the 'clean' directories you made.

After all this fun then you need to go back and;

->rpm -Uvh --force --nodeps filename.rpm 
# to cause rpm to recognize that the package is installed.

->rpm --rebuilddb
( There are possibly simpler ways but this does work-- I have done this myself 
to fix rpm -the package manager, yum and apt-get from a broken version 
upgrade)

Anyone have a better way I would like to hear it also.
