"core" commands missing (1 reply)

Usinig Piwik 2.0.2
Trying to get automated reports to work - to be sent monthly.

Following instructions on: [piwik.org]
using something like (customised to our installation of course)

/usr/bin/php5 /path/to/piwik/console core:archive --url=http://example.org/piwik/

The cron call fails.
Calling from the command line fails too. I get:

[InvalidArgumentException]
  There are no commands defined in the "core" namespace.

Just calling

/usr/bin/php5 /path/to/piwik/console core

I get:

[InvalidArgumentException]
  Command "core" is not defined.

Doing a plain "console", I get

..piwik/console
