I'm trying to figure out what's happening, but for some reason I don't get any output after 'print $to_gpg':

use strict;
use warnings;
use utf8;

use Data::Dumper;
use GnuPG::Interface;

STDOUT->autoflush(1);

my $gpg_pass = $ENV{'GPG_PASSWORD'};

print Dumper(encrypt("hello world", "swilson"));

sub encrypt
{
  my ($text, $email) = @_;

  return "No data" if (not defined($text) or ref($text) ne 'ARRAY');
print "In encrypt email: [$email]\n";
  my @recipients;
  push @recipients, $email;

  my $oGpg = GnuPG::Interface->new();
  push (@{$oGpg->options->extra_args}, '--keyserver-options', 'no-auto
+-key-retrieve' );
  $oGpg->options->hash_init(
    meta_interactive  => 0,
    always_trust      => 1,
    armor             => 1,
    homedir           => './gnupg',
    recipients        => [@recipients],
  );

  my ($gpg_to, $gpg_from, $gpg_err, $gpg_stat, $gpg_log) =
    (IO::Handle->new(), IO::Handle->new(), IO::Handle->new(),
      IO::Handle->new(), IO::Handle->new());
   
  my $handles = GnuPG::Handles->new(
    stdin   => $gpg_to,
    stdout  => $gpg_from,
    stderr  => $gpg_err,
    status  => $gpg_stat,
    logger  => $gpg_log,
  );

  foreach my $handle ($gpg_to, $gpg_from, $gpg_err, $gpg_stat, $gpg_lo
+g)
  {
    $handle->autoflush(1);
  }

  $oGpg->passphrase($gpg_pass);

  my $pid = $oGpg->sign_and_encrypt(handles => $handles);
print "In encrypt pid: [$pid]\n";
  print $gpg_to @$text;
print "In encrypt HERE0\n";
  close $gpg_to;

print "In encrypt HERE1\n";
  my $raCiphertext;
  @$raCiphertext   = <$gpg_from>;     # reading the output
  my @aErrorOutput = <$gpg_err>;      # reading the error
  my @aStatusInfo  = <$gpg_stat>;     # read the status info

print "In encrypt HERE2\n";
  # Cleanup
  foreach my $handle ($gpg_from, $gpg_err, $gpg_stat, $gpg_log)
  {
    $handle->close;
  }

print "In encrypt HERE3\n";
  waitpid $pid, 0;

print "In encrypt raCiphertext: [" . @$raCiphertext . "]\n";
  return "No data" if (ref($raCiphertext) ne 'ARRAY' or scalar(@$raCip
+hertext) == 0);
  my $result = result_check($email, @aStatusInfo);
  return $result, $raCiphertext;
}
