Bear in mind that these instructions you are seeing from
mysql_install_db5 are generic instructions the MySQL team thinks will
be useful. This instruction to copy the mysql.server script is, of
course, useless for Mac OS X, where we provide a launchctl plist
instead. Perhaps we could patch the script to provide MacPorts-

Ok, so it said right there that you need to start the server first.

So, like it said, you need to start the server before you can install
the initial databases. The port prints instructions for starting the
server when it's done installing, so long as you used the +server
variant, as I said before. The instructions would tell you to run
this command to start mysql5 now and to have it start at every
subsequent system startup:
sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist
The opposite -- stopping mysql5 now and having it no longer start at
system startup -- would be:
sudo launchctl unload -w /Library/LaunchDaemons/

You mean, you don't see instructions advising you to run
mysql_install_db? Those instructions are also only printed if you use
the +server variant. If you do not use the +server variant of mysql5,
it is assumed that you merely want to use mysql to connect to a mysql
server already running on a different computer. If you want to run a
mysql server on this computer, you want +server.
The option to start the mysql server without its privilege system is
--skip-grant-tables but I don't think there's any reason why you
would need to use that.
