MacOS 10.6 here. Could it be this ? new ditto version in it  ?

No, no !

--sequesterRsrc works only with PKZip

Do in a terminal:  ditto -h

Usage: ditto [ <options> ] src [ ... src ] dst

    <options> are any of:
    -X              do not descend into directories with a different device ID
    -c              create an archive at dst (by default CPIO format)
    -x              src(s) are archives
    -z              gzip compress CPIO archive
    -j              bzip2 compress CPIO archive
    -k              archives are PKZip
    --sequesterRsrc copy resources via polite directory (PKZip only)
