(start-dccifd) su: no directory

I installed DCC on a FreeBSD 5.4 server from the ports collection.  I
created a symbolic link called rcDCC.sh in /usr/local/etc/rc.d/ linked
to /usr/local/dcc/libexec/rcDCC.  When DCC tries to start I get an error
when starting dccifd.  The error is 'su: no directory'.  I'm not sure
what this means or how to fix it.  Has anybody run into this problem?
