OK - the fog has slowly lifted here, since I last posted (and mis-descripted) my own contribution.
The release thread:
https://www.mobileread.com/forums/sho...d.php?t=240616
(you only need the base-* archive for the HF runtime)
The How-To Install it and use it:
https://www.mobileread.com/forums/sho...1&postcount=47
(Either over ssh or from inside kterm)
Note: it installs in */esys rather than under */extensions or */system (a pathlength problem in editing elf files).
The 5cent tour:

Although the prompt did not change, the 'exec' replaced your command line interpreter with ash-1.22.1
The first one (Lua) is Amazon's release from their system tree.
The second one (LuaJit) is from the HF system tree.
(Yes Virginia, you can run two (or more) different system library trees on Linux, concurrently (no chroot required)
)
Now try running Amazon's Lua extension module(s):
Code:
[root@kindle us]# luajit

Phooey!
Amazon installed that extension library in:
Code:
/usr/lib/lua/json.lua
And the default search path is looking in (the proper place):
Code:
/usr/share/lua/5.1/json.lua
Note: /usr/lib/*, /usr/local/lib/* is where the binary modules (should) live; json.lua is a source code module.
The same problem will exist for all the Amazon provided library modules.
A quick and very dirty work-around is to copy the module file(s) to the current working directory:
Code:
[root@kindle us]# cd
[root@kindle root]# cp -a /usr/lib/lua/json.lua .
[root@kindle root]# luajit
LuaJIT 2.0.3 -- Copyright (C) 2005-2014 Mike Pall. http://luajit.org/
JIT: ON ARMv7 VFPv3 fold cse dce fwd dse narrow loop abc sink fuse
> require 'json'
>
But that is tiring and error prone.
I should work up a new 'init' file for LuaJit to make its search paths match the Amazon install.
(A WIP)
Well, the source code paths can be handled by:
Code:
[root@kindle root]# luajit
LuaJIT 2.0.3 -- Copyright (C) 2005-2014 Mike Pall. http://luajit.org/
JIT: ON ARMv7 VFPv3 fold cse dce fwd dse narrow loop abc sink fuse
> package.path = package.path .. ";/usr/lib/lua/?.lua"
> require 'sqlite3'
> require 'json'
>
And similar for the C binary search paths.
Why?
Because once fixed, this should deal with the "lua ccat is too slow" comments.
Note:
For the interested, the entry point of the ccat extension module is:
/usr/lib/ccat/init.lua
