I would not recommended that. Always a bad idea.
It will interfere with packaging.

/usr/local is the place where all user-built software
  should be installed.
Two versions of Jack can happily coexist - one in /usr
  and one in /usr/local. Only one can be active at a time
  of course. But it is easy to switch between them.
If you want to switch back to the packaged version simply
  uninstall your user-built version from /usr/local.

Thus I mentioned "sudo ldconfig" /may/ be sometimes
  required (I think it may have been with jack-1) so that
  the system can find (switch over to) the new libraries,
  to be able to immediately start using the new installation.
