Python replacements for RVM/Bundler/Capistrano
pip is 'the' tool for Python packages, replacing easy_install. Most people are using virtualenv for multiple python environments.
I'm just moving over from Ruby/Rails development to Python/Django and i'm trying to find the  best replacements for RVM/Bundler/Capistrano but it seems to be a total mess?
I've found these so far:

pythonbrew
virtualenv
envwrapper
pip
easyinstall
setuptools

For capistrano I've found Fabric which seems to fit fairly well?
I've found some articles describing how to set up virtualenv/pip/fabric but it seems everyone is moving over to pythonbrew? Which ones should i pick? Also it seems pip/virtualenv is integrated fairly well but if pythonbrew is a better choice?
