# Installs gems that are slightly broken
# As a name it expects the name of the gem.
# If you want to want to install a certain version
# you have to append the version to the gem name:
#
# install a version of mime-types:
# rubygems::gem{'mime-types': }
#
# install version 0.0.4 of ruby-net-ldap:
# rubygems::gem{'ruby-net-ldap-0.0.4': }
#
# uninstall polygot gem (until no such gem is anymore installed):
# rubygems::gem{'polygot': ensure => absent }
#
# uninstall ruby-net-ldap version 0.0.3
# rubygems::gem{'ruby-net-ldap-0.0.3': ensure => absent }
#
# You can also set your own buildlfags, which will then install
# the gem in question by the gem command.
#
# You can also enforce to use the gem command to manage the gem
# by setting provider to `exec`.
