/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.
It does not work in my OS (Fedora), After installing jack to /usr/local and
ldconfig, the old jack (rpm-based) is launched. I have /usr/local/bin in my
PATH before /user/bin. Setting LD_LIBRARY_PATH to a directory with jack
libraries also does not have any effect.
The only workable solution I found is building my own rpm and updating the
system installed jack
