Yes, upgrade to R 2.14.0 (now in "RC" = Release Candidate state)
or newer (and don't use Windows).
The 'NEWS' entry is

    • R CMD build on a Unix-alike (only) now tries to preserve dates on
      files it copies from its input directory.  (This was the
      undocumented behaviour prior to R 2.13.0.)

Best regards,
and thanks for persevering ( and *NO thanks* for using Nabble :-( )
