[Routing] Help with routing using Open Street Map Data‏‏

[Craig Timothy Herndon (cthrndon)]

Hello,

          I've been trying to find something that will parse the osm data so that I can treat intersections as nodes on a graph and the distance from nodes as a weight.
I took Jorge's advice and ran into this(link at bottom) by Gary86. After struggling to get perl working on my laptop  I've now run into an issue that should be simple to solve.
In his code there are two lines that reference files that I don't currently have. These two lines are "use OSM::osm 4.0 ;" and
"use OSM::osmgraph 2.0" ; Where can I download osm 4.0 and osmgraph 2.0? 


Here is the link to the file I'm trying to use.
http://svn.openstreetmap.org/applications/utils/gary68/distancemap.pl

P.S. Am I taking the right approach or would you suggest I use something else?


Thanks for all the help,

                                             Craig.
