 Using your example, I believe 4755 or 4600 would do it.[[BR]]
 From man chmod:[[BR]]
  * 4000 (the set-user-ID-on-execution bit) Executable files with this bit
 set will run with effective uid set to the uid of the file owner.
 Directories with the set-user-id bit set will force all files and sub-
 directories created in them to be owned by the directory owner and not by
 the uid of the creating process, if the underlying file system supports
 this feature: see chmod(2) and the suiddir option to mount(8).
  * 2000 (the set-group-ID-on-execution bit) Executable files with this bit
 set will run with effective gid set to the gid of the file owner.

 I am building with these instructions as well. I made separate patches for
 each file and planned on posting them here. I'm still compiling.
