I did this:

# The name of your servers cgi-bin directory
   $config{'cgi_dir'}            = 'cgi-bin'; # Default for most servers
   
# The cgi-bin subdirectory where your eAuction.pl will be stored
   $config{'auction_dir'}      = 'eauction161';
   
# The Path to a 'NON-WEBACCESSABLE' directory of your system
# Maybe you have to chmode it if you use your own setting

  $config{'get_path'}              = 0; # Set this from 1 to 0 if you want to use your own setting  
  $config{'basepath'}              = '/mnt/web_h/d12/s07/b01ea042/cgi-bin/eauction_161/eauction161';

# You need to assign either a mail program or
# a mail host so e-mails can be sent out.
# Configure your MAIL PROGRAM

  $config{'get_mail'}            = 0; # Set this from 1 to 0 if you want to use your own setting  
  $config{'mailprog'}            = '/usr/lib/sendmail'; # no additional options please
 
# or Configure your MAIL HOST (SMTP)
   #$config{'mailhost'}      = 'http://YourSMTP-Host';    
   
# Set this from 0 to 1 if the script is running with a real Web-Server
   $config{'web_server'}      = 1;
   
Plus: in the auction.pl i changed this:
$config{'html_path'} = "$ENV{'DOCUMENT_ROOT'}/www/$config{'html_dir'}";
