      # It's not in trunk yet, but it has been submitted upstream, okayed, and
      # hopefully a version of it will be committed by the time 7.6 comes out.
      # If you're updating this formula for 7.6, email davidbalbert@gmail.com,
      # and I'll let you know if the change has made it into the release.

    gdb requires special privileges to access Mach ports.
    You will need to codesign the binary. For instructions, see:
