Unexpected error when using noarch_python

[jni]

I'm trying and failing to create a conda package for a pure Python library. Building for OSX (my current system) worked fine, but when I added:

build:
  noarch_python: True

to my recipe, I got the following error:

Traceback (most recent call last):

Looks like a dup of this issue ( https://github.com/conda/conda-build/issues/542 ).

Have you tried again with noarch: python?
