I need to use OSC. I had been using mrpeach in pd-extended, but I see that pd-extended is no longer recommended, and it won't compile for my system anyway  (I'm using unbuntu 14.04 on an Udoo), so I have pd-0-46-7 installed. 
I downloaded pd-osc from my package repo, but there is no hint about where udpsend is supposed to come from. There is no pd-mrpeach from my repo either, so I'm currently trying to get the version from https://svn.code.sf.net/p/pure-data/svn/trunk/externals/mrpeach/net/ working without much success. It compiles but I still get "udpsend ..couldn't create". 
What is the correct way to get udpsend? Or is there another way to do OSC?

Cheers,
Paul
