Right, though it seems no one has a description of how the Namecoin client modified the Bitcoin P2P protocol, not just the RPC protocol, so rebuilding it from scratch would be more difficult. I presume a working namecoin client does allow the "rawtransaction" cli command to show some of the detail in a given transaction structure? (the blockexplorer site for Namecoin doesn't show that level of detail). I'm still struggling to get a working client compiled for my OSX box, so can't check myself.

Can anyone help me figure out why I'm getting this compile error trying to build the client? I'm using Macports for the library installations.
