[chef] `render_template': uninitialized constant Chef::Knife::Core::BootstrapContext (NameError) ?

[Denis Haskin < >]

(this may be an issue with some 3rd-party cookbooks I'm using, but I figure I would ask here:)

Does the error below ring any bells for anyone?  Any pointers on where I should be poking to try and figure out why this is happening and fix it?

$ knife cluster bootstrap cm-cassandra datanode mumble.compute-1.amazonaws.com -VV
