Puppet-enterprise-install fails basename: missing operand

I just downloaded the puppet enterprise installer for my OS version and the installer seems to fail immediately. Couldn't find anything online so I would appreciate any help you guys could provide on why it is failing:

sudo ./puppet-enterprise-installer
basename: missing operand
Try `basename --help' for more information.

This is the only output from the installer before it stops. EL6 Is the OS version.
