Root filesystem build failure, No rule to make droid

Sorry if I’m asking in the wrong place! Unsure whether to ask under here or in rowboat.

When I try to build the root filesystem following the instructions here: http://code.google.com/p/rowboat/wiki/JellybeanOnBeagleboard_WithSGX

When I issue make TARGET_PRODUCT=beagleboard droid I see make: *** No rule to make target `droid’. Stop.

Its not working, does it need an underscore?

Thanks
