 some of the mode bits being correct in order to determine which files
 should have mode 0755, etc. Since the exec bits are lost during the 7z
 extraction process, I don't think ddmg.sh will work as-is (but I have not
 tried it).

 I think you are right, `ddmg.sh` is using `find $@ -executable` to find
 which files to change.

 I can see two options to fix this permissions problem:
 - generate the new mar files using the `*-signed.tar.bz2` files instead of
 the .dmg files
 - generate them from the .dmg files, and extract the old mar file to
 replicate the file permissions from the old mar file to the new one
