Just looking at the errors, probably the best thing to do is check a few of
them against
the documentation. Maybe someone knows offhand if they reflect a large API
change- you
said you had an old install along with the new one.
Is there a conversion from Node to Point and if so what is preventing
it? Note that you have requested a Point reference. Did some of the API change
recently?
I won't touch the auto pointers for fear of
a flame war and I was just cursing at a unique pointer or something lol :)
