Cannot build - need libnet dependency

[GoogleCodeExporter]

What steps will reproduce the problem?
1. The required libnet does not seem to have any code at
hg clone https://code.google.com/p/libnet/
It appears to create an empty repository.  Any idea where I can get a copy?
2.
3.

What is the expected output? What do you see instead?
Was expecting to find the dependency where specified.

What version of the product are you using? On what operating system?
Ubuntu 12.04.

Please provide any additional information below.
Just missing a dependency - nfex looks like it will build if I can get a copy 
of libnet.
