Once you did that, you need to include a line like
AM_PATH_LUA()
to check for Lua 5.0 or
AM_PATH_LUA(5.0.2)
to check for a specific minimum version. It adds an option --with-lua-prefix 
to your configure script (by default it tries to guess the Lua prefix by 
fetching the location of the lua interpreter in the users' $PATH). I don't 
know if the version matcher works for Lua < 5, though (it assumes LUA_VERSION 
is a string in the format "Lua x.y.z" or "Lua x.y", don't know if this was 
true back then).
