The question is where that /dev/parport0 might come from.

The "usbtiny" programmer is USB-attached, so specifying a parallel
port for it makes no sense at all.  Do you perhaps have a default
port specified in your .avrduderc?  The official avrdude.conf
entry for "usbtiny" says:

programmer
  id    = "usbtiny";
  desc  = "USBtiny simple USB programmer, 
http://www.ladyada.net/make/usbtinyisp/";;
  type  = "usbtiny";
  connection_type = usb;
  usbvid     = 0x1781;
  usbpid     = 0x0c9f;
;

where it clearly says the connection goes through usb.

Of course, it's always possible to override this from the
commandline with "-P usb", but you might want to find the
actual cause for the misconfiguration on your site.
