tsearch2 question - Mailing list pgsql-sql

In my tsearch2.sql there are statements like :


--dict interface
CREATE FUNCTION lexize(oid, text) returns _textas '$libdir/tsearch2'language 'C'with (isstrict);


I don't think $libdir is the real value that we want. Do I need to set
some special parameters with ./configure (in the root level of the source
tree) to replace $libdir with the real library path?

Thanks
