I've built various debian packages of perlbal recently, but the
changelog in SVN has a version number of 1.41 (whereas we're currently
on at least 1.53 at the moment) - it might be worth updating that
before you build, so as not to confuse yourself later on.

Is there any chance somebody with commit access can keep the changelog
up-to-date? Pavel? (or perhaps adds a script that gets the latest
version number from CHANGES on build...)

Oh, and a minor bug fix, or at least a request for comments on one; We
serve a number of files in directories called things like
'blah...234089', and can't through the perlbal web server as-is. I'm
using the following fix (ie. Don't just check for two '.'s, but make
sure it has slashes around it). Is there anything obviously worse with
this from a security point of view?
