With your help I found the solution. My DB was initially based on a 9.0 server and I had restored it on the 9.1 server. For some reason 9.0 fuzzystrmatch functions (levenstein...) were already present in this DB. So, CREATE EXTENSION fuzzystrmatch did not work. I had to manually remove function 9.0 fuzzystrmatch functions and then CREATE EXTENSION .... worked perfectly and levenstein_less_equal as well. So, it was error from the DB restored from an older version of postgresql.
Just as well my advice turns out to be bogus. The contrib stuff is already loaded into the share/ directory.
