Description of problem:
After running of /etc/cron.daily/prelink at least one symlink in /usr/bin (in my
case pnmdepth) is changed to to content of the file to which it pointed to.

Version-Release number of selected component (if applicable):
prelink-0.3.6-3

How reproducible:
- running /etc/cron.daily/prelink or just prelink
- please note, that this problem does not occur on all machines, but if it
occurs on one, it will happen every time
  
Actual results:
symlink pnmdepth is removed, instead there is a new file with the content of
pamdepth (target of the previous symlink)

Expected results:
prelink should not alter any symlinks

Some days ago I've filed a bug on this issue for netpbm-progs:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=192623

I'm not sure whether this is a problem of prelink, netpbm-progs, both or a
packaging problem. Nevertheless I was surprised that a program just alters some
files in /usr/bin ...
