Ah. Its probably my lazy and old hack to the debian control file that kept the old version number. The code in my debs is hot from the forge. They also don't claim to have built against avavhi, for bonjour discovery. Mine is built and configured (as per default) to use libdb4 for its bundle store, whereas they are (perhaps wisely in a minimalist sense) using a file-system based backing store. They also would appear to have a customised dtn.conf file, whereas my dtn deb ships the stock one. I didn't actually realise they'd posted debs for the DTN2 stuff on their page too. You might be better off with their one for use with DT-Talkie as per their guide.

Is there any sign of the source for DT-Talkie? I got a binary from Tarikal ages ago, but they still don't seem to mention source on their page.
