Problem to install luaposix with 5.1

[Laurent Faillie <l_faillie@...>]

Hi,

I'm facing following error when trying to use LuaPosix w/ 5.1 :

lua dir.lua
lua: error loading module 'posix_c' from file
'/usr/lib64/lua/luarocks/lib/lua/5.1/posix_c.so':
    /usr/lib64/lua/luarocks/lib/lua/5.1/posix_c.so: undefined symbol:
lua_tointegerx
stack traceback:
    [C]: ?
    [C]: in function 'require'
    /usr/lib64/lua/luarocks/share/lua/5.1/posix.lua:2: in main chunk
    [C]: in function 'require'
    dir.lua:1: in main chunk
    [C]: ?

I found several pages on the web but all regarding lua_tointeger
(without 'x'). One of them tell it's probably because the library hasn't
been linked against liblua
(http://web.archiveorange.com/archive/v/Fh9mPAiX2yWziICEhHy4) and it's
true I don't see it at compilation time :

Any clue ?

Thanks
