We can:

die "ERROR: This build script not safe for unattended installs. Please 
notify @{[$self->dist_author]} that they wrote a bad bad Build.PL. 
Please ask them to provide reasonable defaults or switch to the new 
ask() method."
   if $ENV{PERL_MM_USE_DEFAULT}
   && (called_without_default(y_n) || called_without_default(prompt);
