  I had this problem just yesterday!  And I found a solution, at least for
etex.fmt.  These files are generated automatically by tetex if they don't yet
exist, it runs the command "mktexfmt etex.fmt" or whichever other *.fmt file
is required.  To see it happen, remove both the system-wide and the user-local
etex.fmt files:

rm /var/lib/texmf/web2c/etex.fmt
rm ~/.texmf/var/web2c/etex.fmt

then run

etex //end

  When I do that, I see output that starts like this:

/repository/gcc-build/gcc $ etex \\end
This is e-TeXk, Version 3.141592-2.2 (Web2C 7.5.4)
 file:line:error style messages enabled.
 %&-line parsing enabled.

...and ends like this:

---! /home/dk/.texmf/var/web2c/etex.fmt was written by pdfetex
(Fatal format file error; I'm stymied)

  So, you can see for some reason the fmtutil script (mktexfmt is a soft link
-> fmtutil) is choosing the wrong engine to generate the etex.fmt file, and
etex is correct when it complains the file was written by the wrong engine.
To solve this, I would change into the user-local .texmf dir and remove the
busted one it just generated:

cd ~/.texmf/var/web2c
rm etex.fmt

then manually run a corrected version of the command that fmtutil output at
the start of its run above:

etex -ini   -jobname=etex -progname=etex -translate-file=cp227.tcx *etex.ini

and then I get a working etex.fmt, as shown by:

~/.texmf/var/web2c $ etex \\end
This is e-TeXk, Version 3.141592-2.2 (Web2C 7.5.4)
 file:line:error style messages enabled.
 %&-line parsing enabled.

  I don't know why fmtutil chooses the wrong engine, but I believe that is the
entire underlying bug.


    cheers,
