[CentOS] Switching HTTPD ports

I need to run Apache on a port other than 80, 81 or 8080.  My other 
servers are using 80 and 81 (RH 9: 80; Windows Apache: 81).  If I set 
the port in httpd.conf to anything other than 80, I get an error that a 
socket cannot be created for the port.

No doubt it has something to do with security (did not have that problem 
with Win Apache, but Windows is Windows).  Any suggestions on where I 
should look?
