You need to use create(). Please see

The header file has this comment:
//glyphs seems to be an array, and this function will be used so little
that it doesn't seem worth wrapping it to use a container of
Pango::GlyphString.

Feel free to provide a patch, but the GTK+ docs suggest that you don't
need to use it anyway:
http://developer.gnome.org/doc/API/2.0/gdk/gdk-drawing-primitives.html#gdk-draw-glyphs

I guess we need to merge the GTK+ docs into the gdkmm and pangomm docs.
