Comment (by AndrewSwann):

 Thanks, however running {{{sudo rm -rf}}} on this file also gives a
 Permission denied.  The output of {{{ls -lO}}} is
 {{{
 -rwxr-xr-x  1 500  505  -  744 22 Aug 23:11 valtype_gs1_ean13.pcx
 }}}
 Trying to delete the {{{rsync.macports.org}}} directory runs into the same
 problem with this and a few other files.
