Comment (by pguyot@…):

 The bug doesn't seem to be fixed upstream.

 makeicns relied on CGPaletteCreateDefaultColorPalette to create ics8 and
 icl8 icons using Mac's traditional 8 bit color palette. This API is no
 longer available in 10.9.

 Two solutions exist: avoid creating the ics8 and icl8 icons (cf patch
 above) or re-implement the sampling from 24 bit RGB to 8 bit indexed
 colors (the easiest being to do 6 bit RGB, although quality will be
 inferior than what was available in 10.8).
