[PEAK] Small Issue installing Extremes with pip

[Jorge Vargas]

Hello,

I'm writing to ask for a little patch against the Extremes package.
Apparently when building from source Extremes assumes ez_setup is on
the build environment. As shown here
http://svn.eby-sarna.com/Extremes/setup.py?view=markup This together
with the way pip installs things (using sdist) is causing the build of
TurboGears to fail as reported here
http://trac.turbogears.org/ticket/2169

The solution is really simple. All we need is a try/catch block around
the ez_setup of the setup.py which will allow it to continue. if
setuptools is present but ez_setup isn't.
