problem with new beta

["Denis B. Roegel" <Denis.Roegel@loria.fr>]

Hello,

I have installed the new beta and ran it on an old file
which I believe compiled previously (though it has been a long
time since I last tried to compile it). The file now compiles
with 

   texexec test.tex

but with --pdf, I get:

 TeXExec 2.5 - ConTeXt / PRAGMA ADE 1997-2001

            executable : pdfetex
                format : cont-en
             inputfile : test1
                output : pdftex
             interface : en
          current mode : all
               TeX run : 1

This is pdfeTeX, Version 3.14159-14f-released-20000525-2.1 (Web2C 7.3.2x)

? 

Is that normal?

Thanks,
