silly old hostname help?

[trogers]

Hi,

Rebuilding my (Mac OS X Server 10.2.x) server and installing MySQL 
again, I have forgotten how to fix this, which I've seen long ago:

%mysql_install_db
Sorry, the host 'rogers' could not be looked up.
Please configure the 'hostname' command to return a correct hostname.
If you want to solve this at a later stage, restart this script with
the --force option

I believe my hostname *is* in all the right places? e.g., it's in the 
'hostconfig' file; if I type %hostname, I get: 'rogers'.
Hints?

Thank you,

Ted Rogers
