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??
