Uhhhh, what do you get if you do /sbin/ifconfig (with no arguments), you 
should have a section like 

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:13493 errors:0 dropped:0 overruns:0 frame:0
          TX packets:13493 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:10459494 (9.9 Mb)  TX bytes:10459494 (9.9 Mb)

and you should also have an entry like

127.0.0.1               localhost.localdomain   localhost

in /etc/hosts

lack of those two things could definitely cause problems. Also you might want 
to try "ifdown lo" and "ifup lo", those commands SHOULD tear down and bring 
up the lo interface, respectively. Lack of a local loopback interface, esp if 
no other interface is up can cause some subtle and ugly problems. For 
instance I'd be surprised if X would work properly (if at all) without a 
loopback interface.
