Can't cpan Couchbase

[BWorkAct]

Hello I am fairly new to this client. However when I go to install with cpan Couchbase it fails.

Looks like its failing on the couchbasemock

java -jar /root/.cpanm/work/1492799387.2214/Couchbase-2.0.3/t/tmp/CouchbaseMock.jar --buckets=default::couchbase --port=0 --nodes=5 --harakiri-monitor=localhost:38903

if I run that by hand I get:

this was done a fresh install of ubuntu 16.04.2:
followed by apt-get install libcouchbase-dev libcouchbase2-bin build-essential perl
cpan Couchbase
