Title: Use 'yes' rather than 'env' to keep going on a cpan install.

On newer Centos boxes, the env approach does not work. I'm not a cpan expert at all, and don't understand why. Trusty 'yes', however, works on all my centos boxes.

I got a confirmation from https://github.com/mms-gianni that it worked for him as well.
