title: can't get irexec to work on RPi
body: <p>I am trying to use an IR receiver LED driven by GPIO on the Raspberry Pi. 
  I set up the lircd, taught it about the remote with irrecord, irw shows the keys I'm pressing:</p>
  
  <pre><code># irw
  0000000000f94ab5 00 KEY_1 /root/lircd.conf
  0000000000f94ab5 01 KEY_1 /root/lircd.conf
  0000000000f94ab5 02 KEY_1 /root/lircd.conf
  0000000000f94ab5 03 KEY_1 /root/lircd.conf
  0000000000f94ab5 04 KEY_1 /root/lircd.conf
  </code></pre>
  
  <p>yet irexec doesn't do anything. </p>
  
  <p>My ~/.lircrc looks like this:</p>
  
  <pre><code>begin
   prog=irexec
   button=1
   config=echo "Yay"
  end
  </code></pre>
  
  <p>I start irexec like this:</p>
  
  <pre><code># irexec ~/.lircrc
  </code></pre>
  
  <p>and then it seems like it's waiting for input but nothing comes. </p>
  
  <p>How can I check if irexec is getting the keypresses? How can I make it work?</p>
