Apache directories under /var/www
Solution 1:
For an Ubuntu system, the usual place you want to look is the /etc/apache2/sites-enabled directory. The files in there will define how you vhosts are configured. In particular check the DocumentRoot settings for you virtual hosts.
Solution 2:
What is your 'DocumentRoot' set to in your httpd.conf?
It may be set to: DocumentRoot "/var/www/somedir.dev"
