Stemmer integration in tsearch2 / $libdir error

Hello everybody,

After installing the tsearch2 nice and smoothly
and following the steps provided on Oleg"s and
Teodor"s page i come to an abrupt end after:

# Compile and install dictionary
cd PGSQL_SRC/contrib/dict_fr
make
make install

which still seems to work fine!!

Next comes:

sh-2.05b$ psql testdb < /usr/local/pgsql/share/contrib/dict_fr.sql
SET
BEGIN
ERROR: could not access file "$libdir/dict_fr": No such file or directory
ERROR: current transaction is aborted, commands ignored until end of
transaction block
COMMIT

also tried to go directly from the dir:

sh-2.05b$ psql testdb < dict_fr.sql
SET
BEGIN
ERROR: could not access file "$libdir/dict_fr": No such file or directory
ERROR: current transaction is aborted, commands ignored until end of
transaction block
COMMIT

dict_fr.sql does exist in the dir but somehow i can"t get the $libdir
path inserted right?

Is this $libdir thing a path that i'm supposed to set global somehow??
