WARNING: No Oracle libraries for 32 bit ABI found.
Enter location of Oracle 32 bit ABI client?

The current installation of Oracle does not have 32 bit libraries installed.

Currently Oracle does not ship 32 bit library with 11gR2. This may also be the default in higher Oracle versions. To resolve the issue install Oracle client (that comes with 32 bit library) and get 32 bit libraries from there, and then on the library path, make sure to have the 32 bit path prior to lib. For example:

LD_LIBRARY_PATH=/opt/oracle/11.2/lib32:/opt/oracle/11.2/lib
