Wow!  That *is* interesting, especially because this page says:

http://www.inrialpes.fr/planete/people/roca/mcl/ldpc_infos.html

"Our LDPC codec is the only Open-Source, patent free, GNU/LGPL and 
similar, large block FEC codec for the Packet Erasure Channel (e.g. 
Internet) case we are aware of."

Sweet!

What happened when you ran "make" in the rizzo subdirectory?
