Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
* Change to tar.gz file fetch
* Use perl5 automatic PLIST
* Add a patch so this works with Net::DNS 0.69
* Modify dependence on Net::DNS to be >= 0.42 in accordance with distribution
* Bump PKGREVISION
Thanks to wiz@ for help when I got stuck (auto-plist, include order etc.)
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
