How about recompile ruby with the following patch and test Ruby-GNOME
if your platform's ruby uses dlopen.

In my environment(Linux) I found unresolved symbol gtk_xmhtml_set_font_familty_fixed.
To fix it, apply following patch:

Next, gnome_canvas_item_rotate...

I don't fix it yet.

gnome_canvas_item_scale is declared in header file of gnome-libs.
But it is not implemented in any file of gnome-libs-1.4.1.7.
It will cause error also.

Sorry. I didn't test it when I implemented Gnome::Canvas.
