I'm not sure where the defect is, or how to work around it, without getting 
more details.

I've seen problems similar to this, but not exactly the same as what you are 
seeing.  What I have seen before was discussed here:
http://public.kitware.com/pipermail/cmake/2014-October/058868.html

Perhaps you can go over that and see if it applies to you.
In that case, the bug was in install_name_tool, and there was a simple test 
case to demonstrate the bug.  Apple reported that it was fixed in Xcode 6.3.
