Hello,
On a fresh install.
When installing postgis from http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/,
I get an error when I try to execute the command Create Extension postgis;.
I noticed that others also have this problem:
http://gis.stackexchange.com/questions/71302/error-when-trying-to-run-create-extension-postgis
postgres=# create extension postgis;
ERROR: could not open extension control file "/usr/pgsql-9.3/share/extension/postgis.control": No such file or directory
The package is somehow broken.
All the best,
Tudor
