The latest download worked fine with me (except from the 'development bugs' I described above, of course):
extract the http://www.leadwerks.com/physicssource.zip file to a new folder and copy the .dll and .decls file to Blitz3D's "\userlib" directory (avoid to replace single files), then take one of the demos as a reference.
