"Here's why I'm suggesting that - it's better to test out any applications depending on that autobundle first. The best way I've found to build an autobundle is to install the base, then run your stuff. You're probably missing a module, so you install it."
But i won't be missing a module in Perl v5.8.6 if that module is already installed in v5.6.1 (i have both version of perl installed) AND if that module does NOT have XS/C extension, right?
