I remember having similar problems last time I tried to use the graphviz
stuff. Basically, the "parameter-extracting" version that you're calling
instantiates a function that doesn't really exist, hence the linker error.
You have to be more very specific when calling read_graphviz. and pass in
the istream and a dynamic_properties object. I think you can omit the "id"
string. I think that gave me some problems too.
