It's not consistent, anyway. Changing /usr/local to /usr already
requires modifying _both_ src/luaconf.h and the Makefile. Adding
the preferred module installation paths to the Makefile doesn't
make things worse.

This doesn't work for cross-compilation. The built Lua binary may
not be executable on the host platform.
BTW: I've toyed with semi-automatic module installation and came
up with the script below. You can call it with
lua cmodpath.lua my.module.name
and get back:
But it's really guesswork, depending on how Lua was installed and
whether the 1st absolute path element is really the preferred
installation path for modules. I had to drop this due to problems
with cross-compilation and sandboxed installs, too.
pkg-config is widespread on Linux, but not elsewhere. Back to
editing Makefiles by hand I guess.
local function find_abs_sep(p)
local s = string.sub(p, 1, 1)
if s == '/' or s == '\\' then return s end
return string.match(p, "^[a-zA-Z]:([/\\])")
local modname = arg and arg or "?"
if package and package.cpath then
for p in string.gfind(package.cpath, "[^;]+") do
local sep = find_abs_sep(p)
if sep then
io.write(string.gsub(p, "%?", (string.gsub(modname, "%.", sep))), "\n")
io.write("No suitable absolute path found in package.cpath.\n")
io.write("Lua 5.1 required but got ", _VERSION, "\n")
os.exit(1) -- Grrr. 'return x' doesn't set the exit status.
