It looks like you're doing this in perl, so it's a bit off-topic for the list,
but...

This will only catch the output:
$output = `cmd`; 

What you want to do is to check the $? variable after running the command,
like this:
$output = `cmd`;
if( $? ){
    print "gpg returned: $?\n";
    # error handling
}

You'll probably want to look at 'perldoc -f system' on what to do with $? to get
meaningful information.
