Configuring Lager - I get this error: undefined parse transform 'lager_transform'

I'm testing this https://github.com/saleyn/erws_example on R16B03 (both on windows & Ubuntu)

==> erws_example (compile)
src/erws_handler.erl:none: undefined parse transform 'lager_transform'
ERROR: compile failed while processing /home/charles/erws_example: rebar_abort

I've seen this suggestion http://philipcristiano.com/2013/05/27/ordering-of-rebar-dependencies.html

So far, i'm unable to get any headway.

Thanks.
