You have to look for libraries that are linked against stale versions
of (base system) libraries).

This one is bad. (should be linked with libm.so.4 and libz.so.3)

This one too.

In the latter case, it might be possible that libxmms.so.4 is linked against
the wrong version of libm via another variable, so you should check
ldd -a /usr/X11R6/lib/libxmms.so.4 and so on.

So, you chould check all libaries (at least the ones in /usr/local/lib and
/usr/X11R6/lib) and rebuild them.

For example. the following might work (untested)

for i in /usr/local/bin/*.so;
ldd $i | grep libm.so.3 && echo $i >> /tmp/log
done;

cat /tmp/log | pkg_which | uniq gives you the list of packages that need to
be rebuilt.

If you do the same for libz.so.2 libc.so.5 libpthread.so and for
/usr/X11R6/lib /usr/local/bin /usr/X11R6/bin you have good chances to fix your
system.

Note, that this is not the supported way of doing it (it would have been to
forcefully reinstall all ports).
