I tried using this approach to compile elevedb and then tested it by loading the module in the shell
erl -pa ebin it gives the following error

1> l(eleveldb).
{error,on_load_failure}

=ERROR REPORT==== 3-Jun-2015::12:01:07 ===
The on_load function for module eleveldb returned {error,
                                                   {bad_lib,
                                                    "Failed to find library init function: 'ebin/../priv/eleveldb.so: undefined symbol: _nif_init'"}}

on the other hand it works well when compiled manually.
