They are caused by prelinking being used on the system. If prelink
cannot verify the program, then that is reported back to RKH. You have
the choice of waiting, the prelink system will re-prelink the files, and
then the verification will pass. Alternatively, do as RKH suggests, run
the 'prelink' command on the files - or use 'prelink -a' - and that
should take care of it. Or you could disable prelinking completely of
course.
