old program compatibility with FreeBSD 6.1

[Dan Strick]

I just installed FreeBSD 6.1 and had no problems during the basic
installation.  I did a "Custom" install and seleced "All" in the
"Choose Distributions" menu.

When I attempt to run a program compiled on release 5.4 under
release 6.1, the system complains that it cannot find libc.so.5.
On my release 5.4 system, /usr/lib/compat contains old shared
libraries.  On my release 6.1 system, /usr/lib/compat contains
only the aout subdirectory.

Is this a bug in release 6.1?
