when it's like this, localhost becomes the getreel root dir:
NameVirtualHost 127.0.0.1:8888
<VirtualHost 127.0.0.1:8888>
    ServerName getreel
	ServerAlias getreel
    DocumentRoot /Users/petergoodman/Sites/getreel
</VirtualHost>

when it's like this, it says /getreel doesn't exist:
NameVirtualHost 127.0.0.1:8888
<VirtualHost 127.0.0.1:8888>
    ServerName getreel
	ServerAlias getreel
    DocumentRoot /getreel
</VirtualHost>
