By the way does this:

python -m pip install --upgrade pip  # upgrade to latest pip
pip install -f https://nipy.bic.berkeley.edu/manylinux -U matplotlib

work for you to install matplotlib 1.5.1?

Or this, to install 2.0 pre-release?

python -m pip install --upgrade pip  # upgrade to latest pip
pip install -f https://nipy.bic.berkeley.edu/manylinux -U --pre matplotlib

Best,
