[Dev-luatex] building luatex with external lua headers/libs

Hi Taco!

First of all, thanks for the rework of the zzlib stuff, now it is easy
to compile luatex with external zlib libs/headers.

Now there is the wish that we compile luatex also with the external lua
(5.1) libs/headers.

Ok, I tried it, but it doesn't work. My first try on Debian was to
replace all references in the source code to
	../../lua51/
to
	lua5.1
because the header files are found here in /usr/include/lua5.1

This worked out quite well (for luatex-api.c), but it stumbled at
	lua/texluac.c
where you try to load several header files which are NOT shipped in our
lua51 devel packages. I took a look into the original source and there
is written:

  If you want to install Lua locally, then do "make local". This will
  create directories bin, include, lib, man, and install Lua there as
  follows:

    bin:        lua luac
    include:    lua.h luaconf.h lualib.h lauxlib.h lua.hpp
    lib:        liblua.a
    man/man1:   lua.1 luac.1

  These are the only directories you need for development.

So it seems that you use more than they assumed to be useful.

Now the simple question: Do you plan to change this, is there a
realistic chance that this can be achieved?

(Note that is the start, next are all the other libs ;-)

In any case thanks a lot and all the best

Norbert
