404	Padre::DocBrowser::POD 0.37 contains syntax that is only available in perl 5.10.0, so will not pass t\00-compile.t	CSJewell		"I'm calling it ""trunk"" below, meaning 0.37, BTW.

http://www.nntp.perl.org/group/perl.cpan.testers/2009/06/msg4296397.html shows the problem.

The ?+ and *+ ""posessive quantifier"" syntax is a 5.10.0+ only construction - it needs replaced by something that'll work in 5.8.5-5.8.9 or Padre will not install on those perl versions. (I'm willing to call this ""critical"" for that reason.

My best (untested) suggestion on what the line should be instead:
my($doc,$section) = $query =~ m|([!^/]+)(?>(?:/?))(?>(.*))};

I'll explain it by making it a /x regex:

my($doc,$section) = $query =~
 m{([!^/]+)  # Capture anything (at least 1) that's not 
            # a forward slash, then...
   (?>      # Don't backtrack into this.
    (?:/?)  # Grab 0 or 1 slashes, and do not capture them.
   )
   (?>      # Don't backtrack into this.
    (.*)    # Capture anything else.
   )
  }x;
