Please don't top post.  From the mailing list faq (joke by Randy Bush):

A: Because it reverses the logical flow of conversation.
Q: Why is top posting frowned upon?

Short answer:
Recompile all your ports.

Long answer:
To see how polluted your binaries/libraries are, install the 
sysutils/libchk port and run "libchk -v".  You might want to redirect 
that to a file as it is quite verbose (note that firefox and thunderbird 
produce a lot of noise that can be ignored).  The only things that 
should be linked to libc.so.5 are 5.x binaries that you downloaded and 
didn't compile (e.g., the binary port of 'rar').  If you see more 
binaries linked to libc.so.5, you need to recompile all your ports. 
Once that is done, you may delete all unreferenced libraries (according 
to libchk) OLDER than your last build/install world.  Until there is a 
misc/compat5x port, I use the following settings in /etc/libmap.conf so 
I can delete ALL old libraries (but still allow 'rar' to work):

# Work with 5.x binaries
libc.so.5                       libc.so.6
libm.so.3                       libm.so.4
libstdc++.so.4                  libstdc++.so.5

Hope that helps,
