Imagine the scenario: Debian, install lua5.2 + lua5.3 + luajit.
Still one question remains: lua, luac, liblua.a + headerfiles will
overwrite the previous installed files from other lua version, right?

Smart Debian administrators are not using `make install` but build debs after
applying the Debian-specific patches that handles paths and alternatives.

Why not add a version string to liblua.a, lua, luac, .. ?
Why not installing headers in /usr/local/include/lua-5.3 (or similar)?

Which is what Debian does, as you probably know. And also puts static+shared
libraries in $(INSTALL_TOP)/lib/$(MULTIARCH). But these are specific to the
platform and not suitable to a reference implementation that should work as
simple as possible on the widest variety of platforms. No versions and single-
architecture systems are the lowest common denominator. It would confuse too
many other systems to make them behave like Debian.

I think you are right. Its is not the task of a generic lua makefile to fit all possible OSes/distros. Anyway, from a users point of view its is still difficult to install a stable Linux and to get the newest stable lua stuff from the distro. For instance: Debian Wheezy (stable) offers lua5.1 only. Debian Testing has all the bleeding edge lua stuff but seems to lack nessesary hardware drivers. (So i am still trying to find a allways-stable solution with all the lovely lua stuff.) I stop discussing this here because it will become off topic.

Thanks for your answers.
