  This may be the key to the problem.  This error is generated when the
  "format" of the executable program (invoked from the exec() family
  of system calls) is not supported by the kernel.

  It also is possible that Apache is returning this error to suggest that
  it is not supporting perl.

  First, give the command:

       file /var/www/etools/chocolate/html/perltest.pl

  to see what type of file you're trying to invoke.

  Second, try invoking it outside of Apache.

  I suspect that it will run outside of Apache.
  This suggests that Apache is not supporting perl for some reason.

  Thus, your configuration of Apache likely is incorrect.  I apologize
  if this is obvious.  It is possible that the new version of Apache
  that you installed defaults something needed to be "OFF" rather than "ON"
  to increase security.


  You also might try verifying that the program (perltest.pl) is executable
  (mode 755).

  THEN try converting it to a shell script of the same name and see if that 
  works.  If so then this would further indicate that it is an Apache/Perl
  problem.  (You could try turning off the Perl module capability and see
  if it gets invoked as a non-module Perl program.)
