Packaging page doesn't find correct greetings package

[ageorgou]

When Travis builds the Packaging notebook, it seems to find a different version of the greetings package, not the one that is included in the code (or the RITS version of it). Specifically:

• The %pycat magics for the source files show no output
• The command line invocations (greet ...) fail because of a missing module/relative import error

The strange thing is that the code that fails tries to from greeter import greet (no relative import), but all the versions I can see (the one in this repo, the one under James Hetherington's account and the RITS fork -which is what's installed according to the log) all have from .greeter.

I remember this being changed last year, but maybe something changed again since then?

Now fixed by deleting the binaries and other build output from the installed repository.
