Howdy,

The makeindex command is built-in to latexmk so setting a rule doesn't do the job. A platexmkrc file in the same directory as the root .tex file containing the line

$makeindex = "makeindex -s styledindex.ist %O -o %D %S";

(with a blank line afterward) should do the job. Let me know if it doesn't.

Good Luck,
