Cannot upload to arduino bluetooth

When I try to upload a sketch, it times out with error:

Binary sketch size: 896 bytes (of a 14336 byte maximum) hardware/tools/avr/bin/avrdude -Chardware/tools/avr/etc/avrdude.conf -v -v -v -v -pm168 -cstk500v1 -P/dev/tty.arduinoserial -b19200 -D -Uflash:w:/Users/parki/repo/arduino/misc/blink/applet/blink.hex:i

Any ideas welcomed - I'm stumped.
