pltlc and pltlcu problems - Mailing list pgsql-sql

I try this code

CREATE FUNCTION  pltclu_call_handler() RETURNS OPAQUE AS 
'/usr/lib/postgresql/pltcl.so' LANGUAGE 'C';

and get this error

ERROR:  Load of file /usr/lib/postgresql/pltcl.so failed: 
/usr/lib/postgresql/pltcl.so: undefined symbol: pg_get_enconv_by_encoding

anyone help me with this?
