在Mac OS X 10.8.4上使用自制软件和pip安装VirtualEnv

Question

When I install virtualenv using homebrew + pip I get the following warnings:

$ sudo pip install virtualenv
Downloading/unpacking virtualenv
  Downloading virtualenv-1.10.1.tar.gz (1.3MB): 1.3MB downloaded
  Running setup.py egg_info for package virtualenv

    warning: no files found matching '*.egg' under directory 'virtualenv_support'
    warning: no previously-included files matching '*' found under directory 'docs/_templates'
    warning: no previously-included files matching '*' found under directory 'docs/_build'
Installing collected packages: virtualenv
  Running setup.py install for virtualenv

    warning: no files found matching '*.egg' under directory 'virtualenv_support'
    warning: no previously-included files matching '*' found under directory 'docs/_templates'
    warning: no previously-included files matching '*' found under directory 'docs/_build'
    Installing virtualenv script to /usr/local/bin
    Installing virtualenv-2.7 script to /usr/local/bin
Successfully installed virtualenv
Cleaning up...

It seems like virtualenv is installed and working (virtualenv command works etc.) What do the warnings mean though? What exactly is virtualenv_support? Should I be worried about them?

It's a warning from Python's setuptools that occurs when installing virtualenv; it'll happen when installed outside of Homebrew, too. It's not actually a problem.
