Error while loading shared libraries

Assuming you have installed the libraries to /usr/local/lib, which is the default, the correct answer is to run /sbin/ldconfig as root/sudo.

On some systems you will need to add /usr/local/lib to the paths that ld caches, e.g.

echo /usr/local/lib > /etc/ld.so.conf.d/local.conf
