Unable to start mongo3: no such file to load -- mongo/util/ordered_hash

[misaka]

Installed mongo3 with rvm (v.0.1.2) and using Ruby 1.8.7 ... I get this when I try to start mongo3, even without a landscape.yml file:

% mongo3

Looking at the mongo gem that's installed (v1.0.1) I only see these files in lib/mongo/util:

lib/mongo/util/conversions.rb
lib/mongo/util/core_ext.rb
lib/mongo/util/server_version.rb
lib/mongo/util/support.rb
