Thanks Jens,

This is true, however, I want to have a self-contained postscript file, 
or rather, a postscript file I can include in a *LaTeX* document.  (I 
know this is the ConTeXt-list but I expected to find a lot of MetaPost 
experts on this list. :-))

I have tried to add prologues:=2 to the file (which should produce a 
self-contained postscript file), but the resulting PS-file still doesn't 
show the alpha.

BTW, if I replace the $\alpha$ with $x$ I get a postscript file which 
shows the x without running it through mptopdf.
