Problem while debugging using PgAdmin

Hello,

I am using PsotgreSQL version 8.2.5, and using pl/pgsql Debugger for debugging my pl/pgsql functions. My pgAdmin version is also pgAdmin III v1.8.0,  while debugging I am getting below error

==========================================================================================================================

An error has occurred:

ERROR:  could not load library "/usr/local/pgsql/lib/pldbgapi.so": /usr/local/pgsql/lib/pldbgapi.so: undefined symbol: BreakpointInsert

My database server is on linux, and my pgAdmin is on win

==========================================================================================================================

I am just thinking, is it not working because, My database server is linux machine and pgAdmin is on windows XP machine, and are in different machine.

Waiting for reply.

Thanks and Regards
