Dear Asio developers, 

I tried the ICMP ping example (http://www.boost.org/doc/libs/1_40_0/doc/html/boost_asio/examples.html) of Boost 1.40.0, and it fails to work on both Mac Os X Leopard and Snow Leopard, with

marco$ sudo ./ping google.com
Exception: Socket type not supported

I already use many other features of Asio in the project, therefore I would exclude any problem related to compilation, linking, permissions, network visibility, etc.
Is the ICMP feature implemented for Mac Os X platforms? If so, any idea why I receive the exception or where can I start investigating?

Best regards,
Marco De Angelis
