mixing * ports and non-* ports

When I try to restart the server I get the following:
=============
apache2ctl graceful
[Mon Apr 21 12:56:15 2008] [error] VirtualHost *:80 -- mixing * ports
and non-* ports with a NameVirtualHost address is not supported,
proceeding with undefined results
I have inserted the code given into the apache2.conf file.
=============

<VirtualHost *:80>
ServerName my_app.ca
DocumentRoot /var/rails/my_app/current/public
</VirtualHost>

Any ideas? Thanks for the help.

If I change it to <VirtualHost my_app.ca:80> it works fine. I
*really* need to find a good apache book, any recommendations?
