[Rdo-list] Centos 6.5 Staypuft OpenStack Foreman Installer Ruby Error

Hi All, I'm testing the staypuft project in centos 6.5 x86_64 everything is working correctly using an older version: foreman-installer-staypuft-0.0.12-1.el6.noarch.rpm, but if I try with a newer version got the following error: # staypuft-installer /opt/rh/ruby193/root/usr/share/rubygems/rubygems/custom_require.rb:36:in `require': cannot load such file -- highline/import (LoadError) from /opt/rh/ruby193/root/usr/share/rubygems/rubygems/custom_require.rb:36:in `require' from /usr/sbin/staypuft-installer:3:in `<main>' Someone you know what I'm missing?
