ec2test passes successfully without running any tests

ec2 passes without running any tests and without failing!

The error happens because the utilities/ec2 script imports _pythonpath.py from the local branch directory. Even if you run the 'ec2' command from via a symlink, if you run it in the local branch, it will actually pick up the *local* _pythonpath, and start running the older, local copy of ec2test: call it v1. When your branch is copied up to ec2, test_on_merge will check out a fresh copy of devel, and then merge your branch into it. That merge updates your Makefile to the latest version: v2. The ec2 runner then calls the v2 Makefile with your v1 remote.py: fail. The detailed test log will say SUCCESS with a single message:

  "make: Nothing to be done for `ec2_check'."

This bug affects people who have the 'ec2' command linked to 'lp-branches/devel/utilities/ec2', and then run 'ec2' in a branch that has not had the latest 'devel' merged in.

As a workaround, you can:

   a) merge 'devel' into your branch

   b) run the 'utilities/ec2' script from within the branch you are currently testing.
