[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
