[tex-live] frenchb.lua not found

[Daniel Flipo]

Hi all,

I have recently uploaded a new version of babel-french to CTAN which, 
for the first time includes a .lua file. It is now part of TeXLive.

frenchb.ldf and frenchb.lua are both located in
/usr/local/texlive/2013/texmf-dist/tex/generic/babel-french/
which looks fine for me but the frenchb.lua is not found when I compile 
the following basic example with lualatex:

\documentclass{article}
\usepackage{fontspec}
\usepackage[french]{babel}
\begin{document}
Test.
\end{document}

Error message is:

! LuaTeX error cannot open frenchb.lua: No such file or directory

Odd is that
% kpsewhich -engine=luatex frenchb.lua
% kpsewhich -progname=lualatex frenchb.lua
both return
/usr/local/texlive/2013/texmf-dist/tex/generic/babel-french/frenchb.lua

Of course, I checked the permissions (rw-r-r on files and rwx-rx-rx on 
directories).

Thanks for any hint and best wishes,
