Maybe something like this:

find / \( -perm -0001 -o -perm -0010 -o -perm -0100 \) -exec ldd {} \; \
  2>/dev/null |sed -n '/=>/s/.*=> \([^ ]*\).*/\1/p' |sort |uniq >/tmp/a
find / -name "/usr/lib/lib*.so.*" -print |sort >/tmp/b
comm -13 /tmp/[ab]

If I've typed it in correctly it should (after a long while, I guess)
print out all unused shared libraries inb /usr/lib.  If you want to
see if you already miss shlibs which are referenced use "-23" instead
of "-13" in the last line.

I love U*ix tool hacking, ask a Windoze user how he'd found out which
.DLLs he didn't need!  What if it is hard to read & maintain my code,
so what?  It's still fun :-)

Hope this helps...

a couple of hours :-( )
