Great, thanks. The data_files part though seems incorrect; for one thing
each item in data_files can be either a (dir,files) tuple or a plain
string, and for two 'dir' is the output (installation) directory, not
the root of 'files'. Here's the relevant part from my module:

if self.distribution.has_data_files():
    for item in self.distribution.data_files:
        if isinstance(item, basestring): # plain file
            self.filelist.append(convert_path(item))
        else: # an (outdir, files) tuple
            outdir,data_files = item
            self.filelist.extend(convert_path(f) for f in data_files)
