Thanks, Taco.

After installing ConTeXt 2008-08-04, I have cont-en.fmt in
texmf-var/web2c/pdftex
and
texmf-var/web2c/xetex

Installing ConTeXt 2008-08-15 has the same files in the same places,  
though I gather that it replaces cont-en.fmt in
texmf-var/web2c/pdftex
with as
TeXExec | tex: 14/08/2008 09:34:24 > /usr/local/texlive/2007/texmf-var/ 
web2c/pdftex/cont-en.fmt (7381076)
would indicate.

ConTeXt 2008-08-04 2 works. All later versions do not because of the  
mismatch in base files.
