I tried to follow the install instructions for blockstack core:
$ brew install gmp libffi openssl
$ sudo pip install --upgrade pip
$ sudo pip install blockstack --upgrade
But get the following errors:
Collecting jsonpointer>=1.9 (from jsonpatch<2,>=0.10->warlock>=1.3.0->blockstack-profiles>=0.14.1->blockstack)

Found existing installation: six 1.4.1
DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
Uninstalling six-1.4.1:
