You don't need to "bind" icu to mapnik. Mapnik already links against and uses icu to handle text direction issues. Basically is ubidi_getVisualRun() returns UBIDI_RTL then mapnik should use right-to-left rendering for that string. What it doesn't do at the moment is shaping (except for Arabic) as icu does not appear to support that for any other languages. Pango does support shaping for other languages, and I have been thinking about trying to make mapnik use that instead of icu but I haven't got beyond the thinking about it stage yet.
