I am trying out ConTeXt for the very first time, hoping to assess
whether it's worth re-tooling from LaTeX for authoring scientific
textbooks.

I am using a fresh installation of TeX Live 2009 (installed via MacTex
on a MacBook running Mac OS X 10.6), and I'm trying to process a
sample file I downloaded from one of the ConTeXt web pages.
Unfortunately, the process generates a couple of cryptic warnings
("Lua binary way out of date")  and a fatal error ("can't find
...dcc/formats/cont-en.luc").  I wonder if someone can examine the
input file and the log file (both attached) to help me understand what
I have to do to clean things up and, if possible, why the TeX Live
ConTeXt configuration doesn't work correctly "right out of the box" to
begin with.

  Thanks,
  Grant
