Comment (by pguyot at kallisys.net):

 I'm wondering why I'm the owner of this bug. Judging from the style of the
 comment, I don't think I'm the one who put that in...

 Anyway. Prebinding is useless on 10.4 and while we have issues with 10.5,
 I am a definitive supporter of the "current release + previous release"
 support and therefore would advocate removing all remainings of the
 LD_PREBIND stuff. I can put a .diff here if this helps, or commit the
 thing myself.
