how fix lib when rpm verification fails? prelink?

[Dave Burns]

 rpm -VV mesa-libGL
prelink: /usr/lib/libGL.so.1.2.#prelink#.OzfHpZ Could not trace symbol resolving
S.?.....   /usr/lib/libGL.so.1.2

S means wrong size, ? means it could not be opened for verification.
The file exists and is owned by root, I ran rpm as root. So I am
confused. Has something to do with prelink?

 ls -la /usr/lib/libGL.so.1.2
-rwxr-xr-x 1 root root 441920 Jan 24  2007 /usr/lib/libGL.so.1.2

 Do I need to kick prelink into action somehow? Or just find a copy of
the rpm and reinstall?

Thanks \
Dave
