Error installing from local repo

I'm trying to run this cookbook(2.6.4) on node RedHat without Internet access. So, even setting the package_url attribute to a local repo with the RPM package, it is trying to install gems from RubyGems.org repository.

chef-client log:

And even with the gem installed locally, it continues to trying to install the gem:

# /opt/chef/embedded/bin/gem list mixlib-install
*** LOCAL GEMS ***
mixlib-install (0.8.0.alpha.8)

Am I doing something wrong?

Thanks very much.
