UPDATE: This is no longer necessary with Python3.4. It installs pip3 as part of the stock install.
I ended up posting this same question on the python mailing list, and got the following answer:
# download and install setuptools curl -O https://bootstrap.pypa.io/ez_setup.py python3 ez_setup.py # download and install pip curl -O https://bootstrap.pypa.io/get-pip.py python3 get-pip.py
Which solved my question perfectly. After adding the following for my own:
cd /usr/local/bin ln -s ../../../Library/Frameworks/Python.framework/Versions/3.3/bin/pip pip
So that I could run pip directly, I was able to:
# use pip to install pip install pyserial
# Don't want it? pip uninstall pyserial
