use your system's package manager to install "python-setuptools" and "python-virtualenv" (not sure if these are the actual package names).,it gets installed to python2.6. How can I make it to install the package to python2.7? Is there any option? ,Activate your virtualenv, and install Python packages using pip on it.,As a rule of thumb, you should not use both the packages installed via pip/setuptools, and packages available to your distro (via apt-get, yum, urpmi, etc...) as they might conflict.

Virtualenv does feature a "--help" switch to help you, but you basically do:

$ virtualenv -p <path-to-python-interpreter>
   <environment-dir>
      $ source <environment-dir>/bin/activate
