[erlang-questions] EXMPP and Rebar

[Chris Clark]

Hi

I am trying to use this (https://github.com/Zert/exmpp) rebar-ized fork of
EXMPP with rebar3.

I can compile and generate a release but when I try to run the release
starting exmpp give the error:

{error,{exmpp,{{shutdown,{failed_to_start_child,stringprep,

{port_driver,load,{open_error,-10},exmpp_stringprep}}},
               {exmpp,start,[normal,[]]}}}}

=INFO REPORT==== 9-May-2015::15:54:25 ===
    application: exmpp
    exited: {{shutdown,
                 {failed_to_start_child,stringprep,
                     {port_driver,load,{open_error,-10},exmpp_stringprep}}},
             {exmpp,start,[normal,[]]}}
    type: temporary


Does any one know what I may be doing wrong?

Thanks in advance.
