<p>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?</p>

<p>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:</p>
<pre><code># 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,

<p>Seems like we need to add an #ifdef in luaX_pcall and fallback to the old behaviour if Lua is too old.</p>

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