This looks good, other than some sketchy code in
svn_swig_pl_info_receiver and the lack of any log message at all.

Your current implementation of svn_swig_pl_info_receiver looks like this:

/* Thunked version of svn_client_info_t callback type. */
svn_error_t *svn_swig_pl_info_receiver(void *baton,
                                       const char *path,
                                       const svn_info_t *info,
                                       apr_pool_t *pool)
  svn_error_t *err = SVN_NO_ERROR;
  swig_type_info *infoinfo = _SWIG_TYPE("svn_info_t *");

  if (!SvOK((SV *)baton)) {
    return ;

  svn_swig_pl_callback_thunk(CALL_SV, baton, NULL, "sSS", path, info,
                             infoinfo, pool, POOLINFO);

So you declare an error variable, but never use it. Worse, the
function returns an svn_error_t *, but in the error case you return
nothing at all and at the end of the function you don't return
success. I'm not all that clear on the right way to write these
functions in the bindings, but that seems wrong to me.

As far as a log message, http://subversion.tigris.org/hacking.html
should have all the details you need on how to write one of those.
