hue shader

Hello,
I'm looking for a shader that does hue rotation. ( Incidentally, as so many of the cpu based objects already exist in shader-land in the standard distro, that poor little shader is conspicuous in its absence. )

I found two earlier threads regarding this, with the following shaders posted: cc.huerot.jxs, and v001.hue.jxs. Other posters in those threads commented that these shaders didn't work on their machines. That is the case for me as well (OS X 10.5.6, Max 5.0.4).

So, I suppose my post breaks down to these two things: 1) a feature request: if Jitter developers feel like adding a hue rotation shader to the standard distro, that would be awesome, and 2) in the absence of 1 above, does anybody have any recommendations for hue rotation that don't involve the previously mentioned two shaders (or have tricks to make those shaders work?).

Many thanks,
Michael
