couchbase-cli server-eshell fails if erl isn't in the path..

couchbase@186b07ee63a6:/opt/couchbase/bin$ ./couchbase-cli server-eshell -c 127.0.0.1:9000 -u Administrator -p asdasd
ERROR: command: server-eshell: 127.0.0.1:9000, [Errno 2] No such file or directory

The error isn't very intuitive for the user because at first I searched around for something called server-eshell (assuming that the couchbase-cli would exec another tool to handle the request).

What it actually fails doing is to execute the erl binary (see info.py):

p = subprocess.call(['erl', '-name', name, '-setcookie',
cookie, '-hidden', '-remsh', node])

I would assume that the erl we want to use is the same erl the rest of our system is using? (which would be installed in the same directory as couchbase-cli on a normal installation).
