sudo /sbin/ldconfig -v

ldconfig creates the necessary links and cache to the most recent shared 
libraries found in the directories specified on the command line,
in the file /etc/ld.so.conf, and in the trusted directories (/lib and /usr/lib). 
The cache is used by the run-time linker, ld.so or ld-linux.so. 
ldconfig checks the header and filenames of the libraries it encounters when 
determining which versions should have their links updated.
