The sooner 'Project Builder' can create perl or shell projects directly the better.
What sort of projects? A simple .pl file doesn't really need a project - it's just a single file. You can use PB to edit it, although BBEdit is arguably a much better editor for that.
If you're looking for full-scale apps, rather than single .pl files, you should have a look at CamelBones. With it, you can create Cocoa apps in Perl. And yes, it comes with app templates for Project Builder.
