I'm running this role against Red Hat 7 and seeing this error:

TASK [zzet.rbenv : install build depends] ******************************************************************************
failed: [staging] (item=[u'bzip2', u'gcc', u'git', u'libffi-devel', u'libyaml-devel', u'openssl-devel', u'readline-devel', u'zlib-devel']) => {"changed": false, "failed": true, "item": ["bzip2", "gcc", "git", "libffi-devel", "libyaml-devel", "openssl-devel", "readline-devel", "zlib-devel"], "msg": "No package matching 'libyaml-devel' found available, installed or updated", "rc": 126, "results": ["No package matching 'libyaml-devel' found available, installed or updated"]}

Adding the following task (to be run as sudo user) seems to get me past it:

shell: yum-config-manager --enable rhel-7-server-optional-rpms
become: yes
