Log Message:
MAKE_JOBS_SAFE=no, and following failures will be fixed.
* native modules may not be linked against libsvn_swig_perl-1, because module
  Makefile may be created before creating the library, and not found.
* inversely, libsvn_swig_perl-1 of previous version may found, but cannot linked
  because of buildlink sandbox.

Bump PKGREVISION (for safe side with update of patch for Makefile.PL).
