There is elfdump, but I don't see how it helps in this case. The only 
information you can get from NEEDED are the base names of the libraries, and 
RPATH reports (typically) the single ${PREFIX}/lib path, so you can't get a 
full list of "what's required from where", let alone identify which libs are to 
be ignored for the REQUIRES meta, for they are in fact part of the PROVIDES 
meta.

Or am I missing something?
