test upstream change to LPRng

[geofft]

Upstream took a somewhat different patch to fix compiling on Natty (and Sid?) than I submitted. We should test it on Natty and make sure it works.

If so we should get Debian to take the patch, and get Ubuntu to sync it from Debian once that happens, dropping the Ubuntu patch (Ubuntu wasn't patching lprng until  lp:719181). One easy way to get Debian to take the patch is to make sure that 3.8.B will include it, and then get Debian to just update to the latest upstream.

So, we lamed on this and now 3.8.B has now been released, but "configure --enable-kerberos" works just fine for me (after installing libkrb5-dev) out of the box, so I think we're good. Someone else should verify, but I'm going to re-milestone.

Someone who has more experience than me working with upstream should figure out what we need to do to get Ubuntu to take this.
