[Ifeffit] Athena problem on MacOS 10.15

Hi All,
  I am using demeter on Mac OS 10.15 (the latest release) and am encountering some problems that I was hoping could be cleared up, in particular with Athena. The Athena version is 0.9.25, the latest version from MacPorts.  Athena starts and properly plots existing projects without trouble, but trying to open a new data set using the PFBL12C plug in. From the Perl error messages below, it appears that the underlying cause is not from the Plugin, but from some problem within Demeter, with an uninitialized values in particular at line 115 that starts with the “my $text” assignment.  Any ideas on what could be going wrong or what other debugging information might be useful.

sub get_array {
  my ($self, $suffix, $part) = @_;
  $part ||= q{};
  if (not $self->plottable) {
    my $class = ref $self;
    croak("Demeter: $class objects have no arrays associated with them and are not plottable");
  };
  my $group = $self->group;
  my $text = ($part =~ m{(?:bkg|fit|res|run)}) ? "${group}_$part.$suffix" : "$group.$suffix";

  my @array = $self->fetch_array($text);
  return @array;
};
