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.

Hi Alan,

FatalError      : Your format does not match the base files!

FilesVersion    : 2008.08.09 18:12

The updating process included

sudo texhash
sudo texexec --make --all

so I am puzzled about why the problem occurs.

There are really only two options:

a) texexec --make --all failed
b) the new format is generated in a different place from the
   old one and the old one is still found first.

In both cases, searching your disk for files named "cont-en.fmt"
should shed some light on the problem.

Best wishes,
Taco
