Installing graph-tool on OSX 10.10 with homebrew

I attempted to install graphtool using the following commands:

brew tap homebrew/science
brew install graph-tool

The install finishes successfully but when I import graph_tool, I see the following 'Symbol not found' error:

After reading about this a bit, I thought there might be an issue with different compilers being used to compile boost versus graph-tool. I uninstalled boost, boost-python, and graph-tool and re-installed, compiling from source.

brew -v install --with-icu4c --build-from-source --with-c++11 boost
brew -v install --with-icu4c --build-from-source --with-c++11 boost-python
brew -v install --build-from-source graph-tool --without-scipy --without-matplotlib --without-numpy

boost and boost-python were successful, however graph-tool fails:

Any ideas on how to proceed from here to get graphtool working?
