Lots of ppl have this problem lately.
Firstly, I don't see a mysql binary file in /usr/bin!
Check the location of the executable file.
if not, to the error...
is line 93 (or a line nearby and before 93) refering to an address that does not exist?
Maybe it is expecting mysql to be installed in /usr/local/mysql..
Try linking the files to where the program is looking for them.
ln -s filename.directory to /link-directory/filename.directory will create a link(shortcut in m$ speak)like this...
ln -s /usr/lib/mysql/libsqlclient_r.so /usr/local/lib/mysql/libmysqlclient_r.so
But especially find the sql daemon and see if it is started at boot, and
find the mysql executable binary, that should be in /usr/bin or /usr/local/bin
You can check the mysql service with...
service mysql status
to start it
service mysql start ,.. restart, stop, etcetera.
All I got, all the best, Glenn
