llWind Rotate Object Help Needed

I have a problem that hopefully will be simple to solve...I'm
out of things to try...

The script below is the standard bit for rotating an object on
the z-axis. It works fine.

But I want to rotate the prim on y-axis. This is for a wind gauge
that is vertically oriented so that North would point to 12 o'clock (up),
South to 6 o'clock, East to 3 and West to 9:

default
{
state_entry()
{
llSetTimerEvent(2);
}
timer()
{
llSetLocalRot(llRotBetween(<1, 0, 0>, llWind(<0.0, 0.0, 0.0>;)));
}
}

Thanks for any help...

Lots of ways to do this... probably simplest is just to use a prim type that looks right when rotated about Z (perhaps a tube instead of a cylinder?)... but just for fun, here's one scripted way:

CODE

default
{
state_entry()
{
llSetTimerEvent(2);
}
timer()
{
llSetLocalRot(<0, 0.70711, 0, 0.70711> * llRotBetween(<1, 0, 0>, llWind(<0.0, 0.0, 0.0>)));
}
}

That cryptic rotation is just llEuler2Rot(<0, PI_BY_TWO, 0>;), by the way; just flipping the rotation 90 degrees. My natural inclination would have been to do the trig in the script, but llRotBetween is probably faster, actually.
