Setting the IO direction won't help if the given port pins are set to
peripheral mode. I believe that all of the msp430 TinyOS platforms set the
Port6 pins by default to module function (aka ADC).
Assuming this invocation has been made:
TOSH_ASSIGN_PIN(GIO0, 6, 0)
Then you can use:
TOSH_MAKE_GIO0_IOFUNC()
to put the pin into IO mode. Now, a call to
TOSH_MAKE_GIO0_OUTPUT()
will make a difference on the physical pin's state.
See $TOSDIR/chips/msp430/msp430hardware.h for details.
BTW, if you're using TinyOS-2.x, you might want to look at using the Low Level
IO componentry instead, as defined in TEP 117 section 2. Low level IO
componentry affords a more modular way to connect logic to digital IO
resources.

Sorry, can't help you with this one.
