[Tile-serving] [openstreetmap/osm2pgsql] src/lua-utils.cpp:154:5: error: ‘luaL_traceback’ was not declared in this scope (#1151)

[gen2]

> It works on Lua 5.1.4 (LuaJIT 2.1.0-beta3), possibly they have backported some features from 5.2. Can you try with 5.2 or LuaJIT instead?

i tried luajit w/ lua52compat enabled, but since their header files are in /usr/include/luajit-2.0 it still failes. But at least luaL_traceback is supported:

```
# fgrep -rn luaL_traceback /usr/include/luajit-2.0/
/usr/include/luajit-2.0/lauxlib.h:85:LUALIB_API void luaL_traceback (lua_State *L, lua_State *L1, const char *msg,
```

As this isn't part of our unit tests, I'm very reluctant to implement it here, and would rather disable stack traces for 5.1. Also, our installation instructions assume Lua 5.2 everywhere (or LuaJIT).


What about a checking for sufficient lua version (and throwing an error) before starting the compiler?
