Ferret looks for shared object you have to create Symbolic Link like this here is example
# Search for object available
[akshay@aix ]$ ldconfig -v | grep libreadline*
libreadline.so.7 -> libreadline.so.7.0
# Locate where it is
[root@aix ]$ locate libreadline.so.
/lib64/libreadline.so.5
/lib64/libreadline.so.6
/lib64/libreadline.so.7
/lib64/libreadline.so.7.0
# Create Symbolic Link[root@aix ]$ ln -s /lib64/libreadline.so.
6 /usr/lib/libreadline.so.6
You might have higher version of shared object, doesn't matter symbolic link is important
