cups at bootup

[Andrew L. Gould]

After a complete system and port upgrade, cups does not start at
bootup. During bootup, I see the following line:

Usage: cups {reload|restart|start|status|stop}

The command 'ps ax | grep cups' returns nothing. If I start cups as
root manually ('/usr/local/etc/rc.d/cups.sh start'), the cupsd
scheduler is started successfully and I can print.

Where should I look for the problem during bootup?

Thanks,

Andrew Gould
