[MonoTouch] Error building/deploying since last update

[Matthieu Laban]

Hello Rolf,

The hostname is KVNY, the name of my machine.

I added an entry for it in my /private/etc/hosts file (127.0.0.1  KVNY) and
it now works (both test.cs and deployment). Not sure why it wouldn't
resolve the name of the machine...

Note that I can't even ping KVNY without this entry in the hosts file.

Thanks for your help and let me know if you need me to test anything else.
Matt
