I think you're misusing the backticks in your code.
my $gpg_command = `gpg --trust-model always -er 12345678 my_file.txt`;
print defined($gpg_command) ? $gpg_command : "Command failed\n"
capturing the output from the command and then printing it to STDOUT.
But in your open command, you're effectively trying to open a pipe to a command that matches the output from your original backtick command, which should be failing I'd think.
remember that backticks do execute your command, and things get a little simpler. For example:
my $fh = FileHandle->new('capture.out',"w");
print $fh `dir`;
This @ISA my( $cool ) %SIG
