The generated command method is an instance method on the provider. You can
instantiate the provider and then call the method:
1.9.1 :005 > require 'puppet'
=> false
1.9.1 :006 > gem = Puppet::Type.type(:package).provider(:gem).new(nil)
=> (provider=gem)
1.9.1 :007 > gem.gemcmd("list")

If you want to try to use the Puppet::Provider::Command class directly you
do:
1.9.1 :011 > cmd = Puppet::Provider::Command.new('ls', '/bin/ls',
Puppet::Util, Puppet::Util::Execution)
=> #<Puppet::Provider::Command:0x007fd22d80abe0 @name="ls",
@executable="/bin/ls", @resolver=Puppet::Util,
@executor=Puppet::Util::Execution, @options={}>
1.9.1 :012 > cmd.execute()
=>
