pdlua has a new maintainer
I started pdlua in 2007, but in the last few years it dropped down my priorities with little new developments. Martin Peach has picked up the ball and is continuing the project in the pure-data externals SVN repository:
svn repository browser at sourceforge
svn co http://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/externals/loaders/pdlua/
Bug reports and patches are best sent to the Pure-data development mailing list.
The pdlua project on Gitorious is now deprecated.
