Trouble installing src.rpm

I'm have trouble installing this package: # rpm -i /home/myhome/bin/MySQL-5.0.16-0.src.rpm warning: /home/myhome/bin/MySQL-5.0.16-0.src.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5 warning: user mysqldev does not exist - using root warning: user mysqldev does not exist - using root # I installed '/home/myhome/bin' as the first installation source in Yast. When I install using Yast I get the message 'MySQL not found on medium'. I'm using a clean install of Suse 10.0 How do I use rpm and/or Yast to install this package? Thanks, Jerome
