Okay, I tried that, but it does not change anything. BTW, for the sake
of completeness this is with CMake 2.6.2.

That is probably correct, but I don't think this is the problem here.
In fact, the library that I am trying to get RPATH'ed into the binary
sits in /opt/std/4.2.4/snos/lib64. If I dump the contents of
CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES I get
"/lib;/usr/lib;/usr/lib32;/usr/lib64".

Any other ideas as to why the RPATH isn't getting set in the binary?
