In addition to Jorn's advice, check /etc/defaults/rc.conf.  The
file should exist and have permissions like so:

$ ls -l /etc/defaults/rc.conf
-r--r--r--  1 root  wheel  31735 May 15 18:48 /etc/defaults/rc.conf

and it should have the following line within:

$ grep lo0 /etc/defaults/rc.conf
ifconfig_lo0="inet 127.0.0.1"   # default loopback device configuration.

If all these aren't true, that would explain why the loopback isn't
configured.
