Bruno, CLUAINPUTS defines directories where you can put shared
libraries which can be used by LuaTeX.  The directory doesn't exist
because no such libraries are shipped with TeX Live (yet?).  Since
shared libraries contain machine code, they have to be somewhere below
SELFAUTOLOC (imagine a tree with the root at the top :).  You can
safely ignore CLUAINPUTS.

I don't know why texdoc doesn't work.  In order to to find out what
goes wrong it's best to set the KPSEDEBUG env var with an appropriate
value for debugging.  I also don't know whether TEXMFCNF is the
culprit but I don't think so.

However, it *is* very easy to add a directory tree with other binaries
iff you have a (multiplatform) TeX Live installation from tug.org and
have write permissions in /usr/local/texlive.  The latter should be
true if the computer is yours.

It's very simple. Assume your platform is i368-linux:

  cd /usr/local/texlive/2016/bin
  cp -a i368-linux my-i368-linux

That's all.  Now you can replace the luatex binary in


There is no need to touch any config file.
