The offending lines read:

libnet_t *

In C, this declares a function that may take an arbitrary number of 
arguments (for historical reasons). In C++, it declares a function that 
takes no arguments at all.

To avoid these differences, one should always write:

libnet_t *

I've fixed that in devel/libnet11/patches/patch-aa.
