Re: obsoleting shlibs - what's the plan

  But here's an idea for a pkgsrc tool: something that would look
  in /bin/*, /sbin/*, /usr/*/*bin/*, /home/*/bin/*, etc., and identify
  all unneeded shared libraries.  A library is unneeded if (a) there's a
  later version of it, and (b) nothing in any tested directory uses the
  older version.

Yes, that would be cool.  And minor versions are always unneeded,
eg. 20.0 can go if 20.1 is present.
