I was able to get the tools working by reverting to 10.5.1 and then installing this patch, however when I upgraded back to 10.6, I was again faced with the same problems. I have a sneaking suspicion that the problem may be that the problem fixed by the patch was not in fact fixed in 10.6 as evidenced by the fact that the bug numbers are not included in the 10.6 Issued Addressed List. If this is the case (I could easily be wrong about this, if a bug is fixed with an optional patch, it may be included in the next update but not listed), I can't fix it in 10.6 because I can't apply a 10.5.1 patch to 10.6.
