conda-smithy: TypeError when using Anaconda API

Hey. I’m still trying to use conda-smithy to build a RC for our own channel. However, I got

TEST END: scikit-learn-0.18rc-np110py27_blas_openblas_202
INFO:/opt/conda/lib/python3.5/site-packages/conda_build/config.py:--keep-old-work flag not specified.  Removing source and build files.

# If you want to upload this package to anaconda.org later, type:
#
# $ anaconda upload /feedstock_root/build_artefacts/linux-64/scikit-learn-0.18rc-np110py27_blas_openblas_202.tar.bz2
#
# To have conda build upload to anaconda.org automatically, use
# $ conda config --set anaconda_upload yes

Using Anaconda API: https://api.anaconda.org
Traceback (most recent call last):

    fname = bldpkg_path(meta)
TypeError: bldpkg_path() missing 1 required positional argument: 'config'

./ci_support/run_docker_build.sh returned exit code 1

The built is here: https://circleci.com/gh/scikit-learn/scikit-learn-feedstock/3

Any help would be much appreciated.
