Based on where the error occured, I'm pretty sure it is communicating
with the stk500 OK.  But for some unknown reason, it just failed to
enter programming mode.

As Joerg mentioned, try getting the verbosity up to the point where
avrdude prints out the actual byte values of the serial conversation
with the stk500.  That may shed some light on what the failure is.  I
think you'll need at least '-v -v -v -v' for that.

Of course, double check that the device is powered and cabled up
properly to the STK500, or if it is in an STK500 on-board socket, be
sure that all the jumpers, etc, are correctly arranged to use that
socket.
