Note: Freetype 2.1.7 doesn't work with GTK+ 2.2.4, so have to use Freetype 2.1.5 instead.
A combination that works:
render 0.8
xrender 0.8.3
fontconfig 2.2.90 [sources]
freetype 2.1.5 [source] (see here for enabling TrueType hinting)
Glib 2.2.3
Pango 1.2.5
Atk 1.2.4
Gtk+ 2.2.4 [sources]
Glib 1.2.10
Gtk+ 1.2.10 [sources]
libpng (use makefile.darwin rather than makefile.macosx)
libtiff
libjpeg v6b (see here for enabling shared libraries)
Libgtkhtml 2.5.5
Librsvg 2.5.0
Libart 2.3.16 [links]
This is helpful too.
