Error in running DBT2

Hi All,

I run the the *dbt2-pgsql-build-db -w 1 *

but, after some time, I faced this error

*/home/abhi/dbt2_install/bin/dbt2-pgsql-load-stored-procs: 45: [: c:
unexpected operator*
*/home/abhi/dbt2_install/bin/dbt2-pgsql-load-stored-procs: 53: [: c:
unexpected operator*
*unknown stored function type: c*

and script ends!!

Moreover, in between the scripts running, i was looing at the ouput i found
something like

Output directory of data files: current directory

*Generating data files for 1 warehouse(s)...*
*Generating item table data...*
*BEGIN*
*ERROR: invalid byte sequence for encoding "UTF8": 0xf9*
*CONTEXT: COPY item, line 1*
*ROLLBACK*

This pattern the above found many times. Please guide me through!!!
