Use the getDirectory() macro function, or IJ.getDirectory() method, to
get the path to the ImageJ plugins directory:
dir = getDirectory("plugins") + "Color/LUTs/";
run("LUT... ", "path=["+dir+"LUTffile.lut]");
The "/" path separator works on all platforms, including windows. A "/"
is always added to the end of paths returned by getDirectory(). The
brackets ("[" and "]") are needed if the path contains spaces. The
getDirectory() function can also get the path to the ImageJ
("startup"), macros, home and temp folders, and to the folder that the
current image was loaded from.

I do not see this problem on Mac OS X and Windows XP.
