Comment (by rjvbertin@…):

 The unified and side-by-side diffs are much more impressive than what
 actually had to be done.

 Michael's version has removed all calls to `install_name_tool` that I
 think the ` compversion440` variant should make for backward
 compatibility. I've found it safer to leave them in.
