I'm not sure if I've gotten past the previous problem, or if I have somehow 
regressed, but I ran into another problem that's got me puzzled.  This time, 
it's keeping the code from even compiling, so I can't be sure if the previous 
problem is resolved or not.

I've added some debugging statements, so the line numbers have changed, but 
this code block is largely still the same:

    181     ruby_block "config_replicaset" do
    182       block do
    183         Chef::Log.info("mongodb:config_replicaset:#{replicaset} 
#{replicaset_name} #{rs_nodes}")
    184         if not replicaset.nil?
    185           MongoDB.configure_replicaset(replicaset, replicaset_name, 
rs_nodes)
    186         else
    187           Chef::Log.info("replicaset nil!")
    188         end
    189       end
    190       action :nothing
    191     end

Can you tell me under what circumstances that you might think that the entire 
replicaset itself could be nil?  By the time we've gotten down to this code 
and extracted the replicaset name and the rs_nodes, it seems that the entire 
replicaset itself couldn't possibly be nil.  Because of this test against 
nil, we are seeing the following problem trying to compile this ruby_block:

FATAL: NoMethodError: ruby_block[config_replicaset] (mongodb::shard line 181) 
had an error: undefined method `length' for nil:NilClass

As you can see, line 181 is the very first line of this ruby_block.  I added 
lines 183, 186, and 187.  But the test of "!replicaset.nil?" was already 
there, and looking at your current code at 
<https://github.com/edelight/cookbooks/blob/master/mongodb/definitions/mongodb.rb>
 I see the same test.
