[pgpool-general: 2310] pgpool-recovery.so ; relocation error; referenced symbol not found

Hi Gentlemen, 
I am trying to execute the pgpool-recovery.sql but being prompted below could not load lib pgpool-recovery.so error. 
Can you please help me to address this? 



bash-3.2$ psql -f ./pgpool-recovery.sql template1 psql:./pgpool-recovery.sql:4: ERROR:  could not load library "/postgres/9.1-pgdg/lib/pgpool-recovery.so": ld.so.1: postgres: fatal: relocation error: file /postgres/9.1-pgdg/lib/pgpool-recovery.so: symbol DirectFunctionCall1: referenced symbol not found

bash-3.2$ ldd -d pgpool-recovery.so
       symbol not found: textout               (./pgpool-recovery.so)
       symbol not found: textin                (./pgpool-recovery.so)
