You should definitely not do that. 

/usr/local/lib and /usr/local/lib64 are for libraries that you compile
locally from source.

/usr/lib and /usr/lib64 are for libraries installed by your distro's
package manager.

Putting anything else there will may confuse the package manager
sooner or later when you do a system update.

The problem is probably that your system is not configured to use
libraries in /usr/local.

To fix this (as root)

1. Move the libraries back to their original locations under /usr/local
2. Using any text editor, Create a file 

in the directory 


The file should contain these  two lines:


3. Run the command ldconfig
4. Reboot

There will be an update of jacktools very soon.
Mostly bugfixes etc. but JackGainctl will change.
The 'rate' parameter in set_gain is no longer supported.
The rate is now fixed to 600 dB/s expect for mute /unmute
which will always take 10 milliseconds.
