Erlang R16B03 (erts-5.10.4) [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

If you run erl to start a shell, and then in the Erlang shell execute m(reltool)., do you see the details of the reltool module? Also, how did you create your reltool.config file? — Steve Vinoski
** exception error: undefined function reltool:module_info/0 in function c:m/1 (c.erl, line 503) — Chinaxing
That error likely means that reltool isn't even installed in your Erlang installation. Unless you really need Erlang version R16B03, I recommend grabbing the latest version, which is currently 17.4, from here, installing it, rebuilding rebar with it, and trying again. — Steve Vinoski

Try to install erlang-reltool, this should help:

$ sudo apt-get update
$ sudo apt-get install erlang-reltool
