We now need to know where some things live on your system. I'll try and make
some intelligent guesses - if I get it right, please just press enter at the
prompt. If I get them wrong, please type in the correct path for me and then
press enter.

First I need to know where the Ezmlm binaries live (ie where I can find
ezmlm-make, ezmlm-sub, etc).

EOM

   *prompt = \&ExtUtils::MakeMaker::prompt;

   foreach (1..10) {
      $ezmlm_path = prompt('Ezmlm binary directory?', '/usr/local/bin');
      last if (-e "$ezmlm_path/ezmlm-make");
      print "I can't find $ezmlm_path/ezmlm-make. Please try again\n";
      if ($_ >= 10) {
         print STDERR "No correct input after $_ attempts.  Exiting Makefile.PL.\n";
         exit (2);
      }
   }

   print << 'EOM';

Now I need to know where Qmail resides on your system. The Qmail base 
directory is the one in which the Qmail bin, control, etc directories
live in.

EOM

   foreach (1..10) {
      $qmail_path = prompt('Qmail base directory?', '/var/qmail');
      last if (-d "$qmail_path/control");
      print "I can't find $qmail_path/control. Please try again\n";   
      if ($_ >= 10) {
         print STDERR "No correct input after $_ attempts.  Exiting Makefile.PL.\n";
         exit (2);
      }
   }

   if(`strings $ezmlm_path/ezmlm-sub | grep -i 'MySQL'`) {

      print << 'EOM';

It appears you have compiled MySQL support into your version of Ezmlm. If
this is correct, I now need to know where the MySQL client (mysql) lives on
your machine.

Please leave this blank if you do not want to enable MySQL support in the
Mail::Ezmlm module.

EOM

      foreach (1..10) {
         $mysql_path = prompt('MySQL binary directory?', '');
         last if (-e "$mysql_path/mysql" || $mysql_path eq '');
         print "I can't find $mysql_path/mysql. Please enter the full path\n";
         print "or leave this option blank if you don't want to use MySQL\n";
         if ($_ >= 10) {
            print STDERR "No correct input after $_ attempts.  Exiting Makefile.PL.\n";
            exit (2);
         }
      }

   }

   print << 'EOM';

Thank you. I will use this information to configure Mail::Ezmlm for you
