Well, it might be helpful to tell the poster how to eliminate the warning.... Since the module in question is a Exporter and DynaLoader, and only the latter has an autoload method, adding the following to the module should work (untested in this form, slightly modified from working code in a different context):

sub AUTOLOAD
{
  my $name = our $AUTOLOAD;
  $name =~ s/.*:://;  # lose package name
  my $target = "DynaLoader::$name";
  goto &$target;
}
[download]

This will get called in Abigail-II's step 4, preventing the warning from step 5.
