Yes, I missed that. Portage just adds to the list of locations 
in /etc/prelink.conf that should be prelinked if PRELINKING is set to yes. 
And during unmerge is runs prelink --undo as already mentioned. So if 
PRELINKING is set to yes then setting it to no is actually all that is 
required:

# head -n 4 /etc/conf.d/prelink
# Set this to no to disable prelinking altogether
# (if you change this from yes to no prelink -ua
# will be run next night to undo prelinking)
PRELINKING=yes

And if it is set to no then `prelink -ua` is sufficient to undo manual 
prelinking.
