How can I use the Boost Graph Library to lay out verticies?

Question

I'm trying to lay out vertices using the Boost Graph Library. However, I'm running into some compilation issues which I'm unsure about. Am I using the BGL in an improper manner? My code is:

PositionVec position_vec(2);
PositionMap position(position_vec.begin(), get(vertex_index, g));
int iterations = 100;
double width = 100.0;
double height = 100.0;
minstd_rand gen;
rectangle_topology<> topology(gen, 0, 0, 100, 100); 
fruchterman_reingold_force_directed_layout(g, position, topology); //Compile fails on this line

The diagnostics produced by clang++(I've also tried GCC) are:

I can never make heads or tails of BGL code either :p When I do need to use it for something I usually check out the included unit-test/example file for the function I want to use. Many times there is an example in there that can be easily modified.
