Bugs

Hi,
I am installing the Postgis 2.2.1 on PostgreSQL.
I am acing the error:


1. Download postgis-1.2.1.tar.gz from
http://postgis.refractions.net/download/
to /usr/share/postgresql/8.1/contrib

2. tar xvzf postgis-1.2.1.tar.gz
cd postgis-1.2.1
./configure --prefix=/usr --with-pgsql=/usr/bin/pg_config --with-geos=/usr/bin/geos-config --with-proj=/usr
make
install
3. # create a PostgreSQL database for a test
createdb zpostgis_test
createlang plpgsql zpostgis_test
- psql -d zpostgis_test /usr/share/postgresql/8.1/contrib/postgis-1.2.1/wpostgis.sql
+ psql -d zpostgis_test -f /usr/share/postgresql/8.1/contrib/postgis-1.2.1/lwpostgis.sql

We now get an error "Could not be loaded liblwgeom.so.1.2"
even liblwgeom.so.1.2 is in /usr/lib.
+
+ Or execute the first SQL statement in lwpostgis.sql:
+ postgres=# CREATE OR REPLACE FUNCTION histogram2d_in(cstring) RETURNS histogram2d AS '/usr/lib/liblwgeom.so.1.2', 'lwhistogram2d_in' LANGUAGE 'C' IMMUTABLE STRICT; -- WITH (isstrict);
+ NOTICE: type "histogram2d" is not yet defined
+ DETAIL: Creating a shell type definition.
+ ERROR: could not load library "/usr/lib/liblwgeom.so.1.2": /usr/lib/liblwgeom.so.1.2: undefined symbol: has_arc



Please provide me the Solution.

Thanks and Regards
