jpegoptim: error while loading shared libraries: libjpeg.so.9: cannot open shared object file: No such file or directory

I am getting these errors
I installed libjpeg 9-c

I can see libjpeg.so.62 in the sbin

i have a plesk setup in centos
when i went to install jpegoptim it complained about no libjpeg - so i downloaded and installed it
this allowed jpegoptim to install

ANy idea what i did wrong?

for those that come afterwards....
as i had to install libjpeg it went into usr/local/lib and seems my plesk system doesnt check usr/local/lib so i needed to edit /etc/ld.so.conf
with
/usr/local/lib
then run /sbin/ldconfig -v (to rebuild cache)
et voila error goes away (i dont know why it couldn't use libjpeg.so.62 which was already installed and as such avoid installing libjpeg.so.9 but thats for others cleverer than me.
