Well I'm the maintainer for that particular external so I will get on it
as soon as I can! It seems that the c API has changed a bit between
versions of lua. I hope the incompatibility doesn't go much deeper or it
will be necessary to have separate [pdlua5.2] and [pdlua5.3]s ;(
So far it looks like lua_load needs to be called with an extra parameter
(NULL will do), and lua_open needs to be replaced by lua_newstate with
two new parameters. Then if it works it will be changed in the
sourceforge svn and at some unknown later time it will be incorporated
into Pd-extended.
Until then maybe just don't build pdlua at all...
