Aha! I'm using gvim with GTK2 GUI which comes (even with "Huge"
features) with -hangul_input -xfontset

Is there a GTK2 package available for Mac OS X? Maybe you could try it?
Or maybe even better, use the MacVim executable developed by Björn
Winckler as a gvim for Mac without X11 (using, IIUC, the Cocoa GUI)? The
MacVim binaries are not kept on the vim.org servers but there is a
chapter about them at http://www.vim.org/download.php#mac

Best regards,
Tony.
