my mistake

gistfile1.cpp

In this case:
"__ZN7WebCore10CanvasPathC1ERNS_4PathE", referenced from:
__ZN7WebCore10CanvasPath6createERNS_4PathE in CanvasRenderingContext2D.o


There's clearly  *something* wrong with my call to the CanvasPath() object.
+    RefPtr<CanvasPath> canvaspath = CanvasPath::create(m_path);


Which directs over to this one:
+    class CanvasPath : public RefCounted<CanvasPath> {
+    public:
+        static PassRefPtr<CanvasPath> create(Path& m_path)
+        {
+            return adoptRef(new CanvasPath(m_path));
+        }
+    Path path() const { return m_path; }
+
+    private:
+        CanvasPath(Path &);
+    Path m_path;
+    };
