upgrading from OMSA 5.4 to OMSA 5.5

Tue Jan 13 11:38:11 CST 2009

I have a PE6900 running CentOS 5.2 and currently has OMSA 5.4 installed 
from the repo.  I tried the instructions at 
http://linux.dell.com/repo/hardware/OMSA_5.5/ and ran wget -q -O - 
http://linux.dell.com/repo/hardware/OMSA_5.5/bootstrap.cgi | bash just 
fine, but I can't get it to update to OMSA 5.5.  yum -y update, yum -y 
update srvadmin-all, yum -y update srv*, etc all don't work.  any ideas?
