Remove psutil from tree, install via install-build-deps.sh

third_party/psutil/README

-
-Introduction
-============
-
-psutil is a module providing an interface for retrieving information on running
-processes in a portable way by using Python.
-It currently supports Linux, OS X, FreeBSD and Windows.
-
-psutil website is at http://code.google.com/p/psutil/
-
-The following document describes how to compile and install psutil from sources
-on different platforms.
-
-
-Using easy_install
-==================
-
-The easiest way to install psutil from sources is using easy_install.
-Get the latest easy_install version from http://pypi.python.org/pypi/setuptools
-and just run:
-
- > easy_install psutil
-
-This should get the most updated psutil version from the Python pypi repository,
-unpack it, compile it and install it automatically.
-
-
-Installing on Windows using mingw32
-===================================
-
-After the mingw [1] environment is properly set up on your system you can
-compile Windows sources by entering:
-
- > setup.py build -c mingw32
-
-To compile and install just append the "install" keyword at the end of the
-command line above, like this:
-
- > setup.py build -c mingw32 install
-
-It might be possible that distutils will complain about missing gcc executable.
-That means you have to add mingw bin PATH variable first.
-Entering this line in the command prompt should do the work:
-
- > SET PATH=C:\MinGW\bin;%PATH%
-
-NOTE: this assumes MinGW is installed in C:\MinGW, if not simply replace the
-path in the command above with an appropriate location.

-Installing on Windows using Visual Studio
-=========================================
-
-To use Visual Studio to install psutil, you must have the same version of
-Visual Studio used to compile your installation of Python. For older versions
-of Python that will be Visual Studio 2003. For 2.6 and later it should be
-Visual Studio 2008. If you do not have the requisite version of Visual Studio
-available then it is recommended to use MinGW to compile psutil instead.
-
-If you do have Visual Studio installed, you can use the basic distutils
-commands:
-
-  > setup.py build
-
-or to install and build:
-
-  > setup.py install
-
-distutils should take care of any necessary magic to compile from there.
-
-
-Installing on OS X
-==================
-
-OS X installation from source will require gcc which you can obtain as part of
-the 'XcodeTools' installer from Apple. Then you can run the standard distutils
-commands:
-
-to build only:
-
-  > python setup.py build
-
-to install and build:
-
-  > python setup.py install
-
-NOTE: due to developer's hardware limitations psutil has only been compiled and
-tested on OS X 10.4.11 so may or may not work on other versions.
-
-
-Installing on FreeBSD
-=====================
-
-The same compiler used to install Python must be present on the system in order
-to build modules using distutils. Assuming it is installed, you can build using
-the standard distutils commands:
-
-build only:
-
-  > python setup.py build
-
-install and build:
-
-  > python setup.py install
-
-
-Installing on Linux
-===================
-
-gcc is required and so the python headers. They can easily be installed by using
-the distro package manager. For example, on Ubuntu:
-
-  > sudo apt-get install python-dev
-
-Once done, you can install/build psutil with:
-
-  > python setup.py install
-
