problem building and/or starting riak

If you want to make it work with 5.7.5, for the moment, you must
simply rename the directory rel/overlay/erts-5.7.4 to
rel/overlay/erts-5.7.5 and then clean everything and rebuild.

In general it's better to use the last released version of erlang than
the head of git repo unless you absolutely need some new feature.
There are typically 4-5 releases of the erlang system a year, so
running most recent release is never very old.

At some point I do need to fix the erts-VSN directory problem. :)
