Can't locate Test/Parser/Dbt2.pm in DBT2 tests

Hi All,

I am conductingDBT2 tests on PostgreSQL. After completing the test while
analyzing and creating the results I am getting following error:

./dbt2-run-workload: line 514: 731 Terminated dbt2-client
${CLIENT_COMMAND_ARGS} -p ${PORT} -o ${CDIR} >
${CLIENT_OUTPUT_DIR}/`hostname`/client-${SEG}.out 2>&1

Test completed.
Results are in: OUTPUT

I ma not sure why it doesn't find Test/Parser/Dbt2.pm even if I have
installed DBT2 completely. Did I miss any steps? Do I need to install some
extra packages? If any then please let me know.

Thanks in advance for your help.

Thanks,
Rohan
