You are right. The example in the website enables elliptic curve
anonymous Diffie-Hellman which doesn't exist in gnutls 2. The error is
subtle because the examples do not include error checking and thus do
not catch the error in gnutls_priority_set_direct().

If you fix the priority string the same example should work as is.
