[luatex] luatex-0.95.0 on Debian - Undefined control sequence: \luatexluaescapestring

[Eduardo Ochs]

Hi all,

I am trying to install luatex-0.95.0 on a Debian system that comes
with a TeXlive in which the version of luatex is:

  beta-0.76.0-2013121407 (rev 4627)

I have the impression that I am *almost* succeeding without applying
the patch to texmf.cnf that Norbert mentioned here:

  http://tug.org/pipermail/luatex/2017-March/006434.html

I am avoiding that patch this moment because I don't understand it
well enough yet =(...

Here is the script that I used, with comments; fmtutil succeeds on
dviluatex.ini and luatex.ini, but fails on lualatex.ini with this
error,

  ! Undefined control sequence.
  \bbl at hook@everylanguage ...\luatexluaescapestring
                                                    {\string #1}') ==
nil)}\if...

I've put a more readable version of all this here:

All hints are welcome...
Here is the script:
