OSX Riak 1.4 Internal Server Error on all map reduce jobs

Homebrew installed Riak will use the Erlang located in this directory:

/usr/local/Cellar/riak/1.4.2/erts-5.9.1/bin/erl

Could you retry the code snippet using the erl located there? Also, the
output of which -a erl could be useful. I think you should uninstall your
homebrew-installed Erlang as it's a more recent version than the one
installed via homebrew for Riak. Personally I use kerl to manage Erlang
versions instead of homebrew.

Thanks
