Basically, its still broken. I actually ran into a bug the other day
caused by the issue where I had prelink enabled locally.

I know Mark is working on some fixes but its an onion problem, you fix
one thing, then find other issues. Mark can give the full story but
right now, its not able to be re-enabled.
