plpython and trusted modules

Hi,

From a plpython function, I'm trying to call a function in a module
that imports _pg (pygresql).  When I do this, I get the following
error:

psql:/home/thoth/dev/data_model/tqse_test.sql:18: ERROR: plpython:
Call of function `__plpython_procedure_test_tqse_198863' failed.
exceptions.ImportError: untrusted dynamic module: _pg

I have added the plpython handler function to the database from which
the call is made with the following command:

    create function plpython_call_handler() returns opaque as
    '$libdir/plpython' language 'C';

I then added the plpython procedural language as UNTRUSTED, with the
command:

    create procedural language 'plpython' handler
    plpython_call_handler lancompiler 'PL/Python';

Why can't I get the stored procedure to execute this function?  From
what I understand of the documentation, I'm doing everything right.
Any ideas?  This is actually a very important problem for me, so any
help would be greatly appreciated.
