Upgrading libs with many dependent ports

FWIW, I some years ago wrote up a quick&dirty perl script to find
missing or out of date libs.  It pulls out and warns about missing
libs, stuff in compat/pkg (held over after upgrade by
portupgrade/portmaster), and stuff in the base /usr/lib/compat (handy
when crossing major versions, and potentially other big upheavals).
It's only about a k; I'll attach it.

I pretty much wind up ldd'ing /usr/local/{bin/*,sbin/*,lib/*.so*} and
running the results through the script.  Usually something like `cd
/usr/local/bin ; ldd * > /tmp/ldd.bin ; lddchk.pl < /tmp/ldd.bin`.
That tells me the files; then I can use my brain or pkg_which to tell
me which packages are involved.  I'm happy with that level of
automation, because I like keeping my brain firmly in the loop on such
things, but it wouldn't be too hard to extend it to do its own walks
over the filesystem, etc.
