Hi Merlijn,
Thanks for taking some time to test our newest feature, charm layers! I
went ahead and tried to duplicate your conditions and ran
http://paste.ubuntu.com/12704459/ which seemed to work for me. I'd like to
get down to the bottom of this, could you let me know what version of
Ubuntu you're running and the output of `pip --version`? Also, as a note
going forward the `charm compose` command has been renamed `charm generate`
and the former will be going away in the next few charm tool releases.
Thanks!
