The rteval utility requires some external software libraries to run
properly. These are:

python-ethtool
  A python library to query network interfaces
  git://git.kernel.org/pub/scm/linux/kernel/git/acme/python-ethtool.git

python-lxml
  A python library to parse XML files and XSLT stylesheets
  http://lxml.de/

python-dmidecode
  A python library used to access DMI table information
  http://www.autonomy.net.au/display/pydmi/Home

libxml2-python
  A python library to parse XML files
  http://xmlsoft.org/

rt-tests
  A collection of programs used to measure real-time behavior
  git://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git


$ sudo yum install python-{dmidecode,ethtool)
$ git clone \
  git://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git
$ cd rt-tests && sudo make prefix=/usr install
$ cd ../rteval
$ sudo make install

That should do it (I hope).
