I think that this patch is corret (well, perhaps execpt for the _smidge_ bit).
I believe that it is general practice for make install and the like to
install shared libraries as executables for the reason that you give
above. Though it is common practice for distros to remove the executable
bit as part of their packaging process - which explains why many
people won't see it when they go and check /usr/lib, but is of little
concern to this patch.
