 Hard to tell. My first *guess* is that there is something wrong with
 Cairo bindings for Python[1] or with the Cairo itself.

 Dear Łukasz,

 Thank you very much for your answer. I installed the latest versions of
 both pycairo and cairo. It seems they are both fine:

   import cairo
   cairo.cairo_version_string()
 '1.10.2'
   cairo.version
 '1.8.8'

 Cheers,
 Luis

[OSM-talk] Pyroute

[Luis Quesada]

Dear all,

(Sorry if this is not the right forum for this question)
I am having error listed at the end when trying to run python gui.py

I am basically following the instructions at :

http://wiki.openstreetmap.org/wiki/Pyroute

svn co http://svn.openstreetmap.org/applications/routing/pyroute/
cd pyroute/
python gui.py

Could somebody tell me what I am doing wrong?

Thanks in advance!

Cheers,
Luis
