Take a look at the log-file and you should see a line like this:

%%%% begin error message
tex error       > tex error on line 8 in file ./test.tex: ! Undefined 
control sequence

<argument> \par draw outlinetext.f ("\frameletter
%%%% end error message

As the error message tells you the command \frameletter doesn't exist, 
you can fix this with \defineframed[frameletter]

%%%% begin example
\defineframed [frameletter]

\starttext

\startMPcode

     draw outlinetext.f
         ("\frameletter{A}")
         (withcolor darkred withpen pencircle scaled 1/10)
         rotated 5 xsized 2cm ;

\stopMPcode

\stoptext
%%%% end example

Wolfgang
