I'll be grateful. But I don't need help with Debian packaging fundamentals. That configure message means something more along the lines that it couldn't find what it needs to build against it, rather than the library itself. As I recall from my own 2.3.0 build, that should do the trick. It's highly debian-specific and backs up dpkg's list of installed packages.
Some beta testing is what it needs before it can get a real release.
I'd like to upload it to sid when someone can confirm that it actually works. It's got a nifty configuration interface which prompts for a few questions and is capable of setting up a client or server. It can even add a cron job. Perhaps it should be debconfized.
