Error when trying to run Create Extension postgis

UPDATE: the TEAM has just released the postgis.2.1.0-3 RPM package that solve the issue: now the extension is available:

/usr/pgsql-9.3/share/extension/postgis.control

END UPDATE. [...]

I resolved compiling POSTGIS from source. This is the step-by-step for CentOS 6.4 64bit:

wget http://download.osgeo.org/postgis/source/postgis-2.1.0.tar.gz
tar xvf postgis-2.1.0.tar.gz
cd postgis-2.1.0
./configure --with-pgconfig=/usr/pgsql-9.3/bin/pg_config --without-raster
make
make comments
make install
make install-comments
su - postgres 
cd /usr/pgsql-9.3/share/contrib/postgis-2.1/
psql -d postgres -f postgis.sql
psql -d postgres -f spatial_ref_sys.sql
psql -d postgres -f postgis_comments.sql
psql -d postgres -f topology.sql
psql -d postgres -f topology_comments.sql

The postgis2_93 RPM provided by http://yum.pgrpms.org/ is missing extension support. I reported this to Devrim earlier this week and he has been attempting to fix it.

http://svn.pgrpms.org/changeset/299

Hopefully the next push of RPMS to the website resolves this.

Update: postgis2_93-2.1.0-3 was released, which solved this issue but placed a rpm requirement for gdal 1.9, which EPEL does not provide. I got it from ELGIS.
