First you must iterate all entities in the model ADD within all definitions entities, and change the layer if it matches...
e.layer=nil if e.layer.name=="layer_to_go"
OR us another layer...
e.layer=layers.add('new_layer')
Now you can do
layers.purge_unused
and the now unused layer is deleted...
If you have an unused layer you'd like to retain you need to make some temporary entities using it, so that layer doesn't get purged.

TIG is being modest, but he actually wrote a snippet for it : http://sketchucation.com/forums/viewtopic.php?t=20086

But don't use it as is, you need to modify it to use the method in your own namespace.
Here is how I did it (There may be some mistakes, I'm just starting ruby ! So check it, but it works fine for me) :

### LAYER DELETE METHOD ### ------------------------------------------------------
	#Simple modification of TIG's snippet delete-layer.rb
	#Basically, move or delete layer content, then creates an entry for every layer except one to delete, then purge layers, then delete entries
	
	def self.deleteLayer(layer, delete_geometry=false)
		model=Sketchup.active_model
		ents=model.entities; defs=model.definitions; layers=model.layers
		model.start_operation ("Delete layer")
		if delete_geometry
			allents=[]
			ents.each{|e|allents<<e if e.valid? and e.respond_to?(;layer)and e.layer==layer}
			defs.each{|d|d.entities.each{|e|allents<<e if e.valid? and e.respond_to?(;layer)and e.layer==layer}}
			allents.each{|e|e.erase! if e.valid?}
		else ### move geom to Layer0 etc
			ents.each{|e|e.layer=nil if e.respond_to?(;layer)and e.layer==layer}
			defs.each{|d|d.entities.each{|e|e.layer=nil if e.respond_to?(;layer)and e.layer==layer}}
		end#if
		group=ents.add_group();gents=group.entities ### temporarily use other layers
		temp=gents.add_group()
		temp.layer=nil
		(layers.to_a-[layer]).each{|layer|tc=temp.copy;tc.layer=layer}
		model.active_layer=nil if model.active_layer==layer ### ensure layer is not current layer
		layers.purge_unused ### purge layer from browser
		group.erase! ### erase! the temporary layer user, use set as was.
		model.commit_operation 
	end#def

Call it with something like self.deleteLayer(layers[layerName])

I think a more popular command would be "Remove Lawyer"...

I did write a whole raft of 'missing' layer methods...
I just thought I'd let you learn by doing...

renderiza

Here is another option but I don't know if its compatible with MAC OS

Sketchup.send_action(21537) #Delete Layer

I learn by looking at what you wrote !
