I just tried this for Gtk2, and it works pretty well:

nm --defined-only --extern-only \
  /opt/gnome/lib/libgdk-x11-2.0.so \
  /opt/gnome/lib/libgdk_pixbuf-2.0.so \
  /opt/gnome/lib/libgtk-x11-2.0.so \
    | grep -v _libgtk_only \
    | grep -v _marshal_ \
    | cut -d " " -f 3 \
    | sort > wanted-api

nm --undefined-only blib/arch/auto/Gtk2/Gtk2.so \
  | grep -v GLIBC \
  | grep -v pthread_ \
  | grep -v Perl_ \
  | grep -v gperl_ \
  | grep -v gtk2perl_ \
  | cut -d " " -f 11 \
  | sort > wrapped-api
