Recursor and LUA: Error loading module md5.core

[anon]

I am trying to use the cryptographic library  http://www.keplerproject.org/md5 in my Recursor LUA script.

The example script:

#!/usr/local/bin/lua
require "md5.core"

This example works well if I start it stand-alone (LUA interpreter). If I try to load it with the Recursor I get this error:

Failed to load 'lua' script from '/root/example.lua': Error loading LUA file '/root/example.lua': error loading module 'md5.core' from file '/usr/local/lib/lua/5.1/md5/core.so':
        /usr/local/lib/lua/5.1/md5/core.so: undefined symbol: luaL_addlstring

I am using PDNS Recursor version 3.1.7.1:

pdns-recursor-3.1.7.1-1.x86_64.rpm
