Mac OS X Lion cannot resolve localhost

Question

I have found serval questions about this but no one helps for me, I am searching for days to get my problem solved but I can't get it done, I hope someone can help me with this big issue.

I try to ping my localhost, I need this to develop my web apps. I do this by zendServer.

This problem cames up when I upgraded my OS X to Lion.

I use internet over Apple timecapsule but I think this doesn't matter to make it able to use your localhost?

Host file (sudo nano /private/etc/hosts):

127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0     localhost

Dig result:

leny-pc:~ nickyklaasse$ dig localhost

; <<>> DiG 9.7.3-P3 <<>> localhost
;; global options: +cmd
;; Got answer:

Host result:

leny-pc:~ nickyklaasse$ host localhost
localhost has address 127.0.0.1
localhost has IPv6 address ::1

Ping result:

leny-pc:~ nickyklaasse$ ping localhost
ping: cannot resolve localhost: Unknown host

I hope some one can help me to an answer.

With kind regards,

Nicky

Solved by running a new clean install of Mac OS X Lion by DVD.
