Clearly the link directories are listed in the wrong order.  This is 
likely a CMake issue which I'll investigate.  It is supposed to 
automatically compute a safe order but there is a bug in that it doesn't 
take into account libraries that will be present after the project 
builds.  I don't know why no one has encountered this before.
