That's due to your missing \starttext

Hm. When you use texexec, after multiple runs (to sort our object refs btw)
the file should be pretty valid.

I wrote this step hack for taco some time ago. It should be hooked into the
styles more comfortable yet. 

% interface=en

\usemodule[pre-green]

\definereference
  [Whatever][JS(NextPresentation{\realfolio})]
\setupbackgrounds
  [text][text]
  [background=TextBackground,backgroundoffset=3pt,]
\setupframedtexts
  [presentationshield]
  [background=color,backgroundcolor=Page]

\enablepresentationstep \autopresentationsteptrue

\starttext

\TitlePage {Slowly We Turn}

\Topic {presentationstep}

\startitemize
  \item moe
  \item larry
  \item curly-joe
\stopitemize

\startformula
  x+5y+10z+25u+50v=100
\stopformula

\stoptext

This should work with your beta. The define and set will go into the style,
since the idea is that you say: 

  texexec --mode=step   %  or autostep

and get the functionality (modes are just pieces of conditional code). I
have to redefine the styles a bit and give the step thing a separate layer
in the background. 

I never thought that anyone would use this stepper -)
