DBT-2 Installation error

Hi

I am beginner with postgres and DBT-2 database .

I am getting many errors with installation of DBT-2(dbt2-0.40)

I followed the instructions in Readme but I am not getting solution.

I build the database according to README. "*build_db.sh -g -w 1"
then I *run the workload "run_workload.sh -d 300 -w 1"

I check the error.log in output/9/Client folder. I am getting these errors.
I run 9 test . I am getting same kind of error in all of them.

Please Help..
