Error while using graph_draw and vorder option

Hi,

I get an error when i am trying to draw the graph using graph_draw and using vorder option. Following is the output:

>>> graph_draw(g_base,vertex_text=g_base.vp["_graphml_vertex_id"],output_size=[2048,2048],output='magdata_qc_viz.png',vorder=g_base.vp["_graphml_vertex_id"])

Here are all the properties of the graph -

>>> g_base.list_properties()
Motif          (vertex)  (type: string)
Energy         (vertex)  (type: long double)
Config         (vertex)  (type: int32_t)
_graphml_vertex_id (vertex)  (type: string)
Y              (vertex)  (type: long double)
X              (vertex)  (type: long double)
_graphml_edge_id (edge)    (type: string)

System: Mac OS X graph_tool installed using macports.

Please let me know if there is any other information required.

Thank you,
