ERROR: schema "madlib" does not exist

For some reason non of my users (not even gpadmin) can access the madlib schema. Does this schema need to be created/enabled first?

tutorial=# SELECT (MADlib.one_way_anova (
tutorial(# CASE WHEN carrier = 'US' THEN 1
tutorial(# WHEN carrier = 'DL' THEN 2
tutorial(# ELSE NULL
tutorial(# END,
tutorial(# arrdelayminutes
tutorial(# )).* FROM faa.otp_r;

Same here, even after manually installing madlib on the image:
wget https://dist.apache.org/repos/dist/release/incubator/madlib/1.9-incubating/apache-madlib-1.9-incubating-bin-Linux.rpm
sudo rpm -hiv apache-madlib-1.9-incubating-bin-Linux.rpm
stop_all.sh
start_all.sh

It still can't find MADlib when trying:
%psql.sql SELECT (MADlib.one_way_anova (
CASE WHEN carrier = 'US' THEN 1
WHEN carrier = 'DL' THEN 2
ELSE NULL
END,
arrdelayminutes
)).* FROM faa.otp_r;

actually just resolved it.
The madly was not installed so I had to download it from:https://network.pivotal.io/. more specifically https://network.pivotal.io/products/pivotal-gpdb#/releases/1683/file_groups/250
Then unpack the tar file and used the gppkg command.
gppkg -i madlib-ossv1.9_pv1.9.5_gpdb4.3orca-rhel5-x86_64.gppkg

The I linked the madlib to the tutorial database:
$GPHOME/madlib/bin/madpack install -s madlib -p greenplum -c gpadmin@localhost:5432/tutorial

and everything worked like a charm through Zeppelin.
