Well you are not saying what error you get. For me (windows 7) the
following works fine with lualatex in a current texlive 2015 and in
miktex. The hyphenations are correct.


\documentclass[]{article}

\makeatletter
\input luababel.def
\def\bbl at add#1#2{%
  \@ifundefined{\expandafter\@gobble\string#1}%
    {\def#1{#2}}%
    {\expandafter\def\expandafter#1\expandafter{#1#2}}}
\def\bbl at csarg#1#2{\expandafter#1\csname bbl@#2\endcsname}%
\long\def\bbl at afterelse#1\else#2\fi{\fi#1}
\long\def\bbl at afterfi#1\fi{\fi#1}
\def\bbl at loop#1#2#3{\bbl@@loop#1{#3}#2,\@nnil,}
\def\bbl at loopx#1#2{\expandafter\bbl at loop\expandafter#1\expandafter{#2}}
\def\bbl@@loop#1#2#3,{%
  \ifx\@nnil#3\relax\else
    \def#1{#3}#2\bbl at afterfi\bbl@@loop#1{#2}%
  \fi}
\def\bbl at for#1#2#3{\bbl at loopx#1{#2}{\ifx#1\@empty\else#3\fi}}
\def\AfterBabelLanguage#1{%

        \wlog{<*languages>}%
        \bbl at languages
        \wlog{</languages>}%
      \endgroup}{}
  \endgroup
  \def\bbl at elt#1#2#3#4{%

  \bbl at languages
\fi
\makeatother
