[graph-tool] Python interpreter too old?

I am trying to install graph-tools, I am using an anaconda version of python 2.7, and for some reason the graph-tools configure throws an error that this version of python is too old: Z:graph-tool-2.2.31 g$ ./configure PYTHON="/g/anaconda/bin/python2.7" CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib" checking whether /g/anaconda/bin/python2.7 version is >= 2.6... no configure: error: Python interpreter is too old Wherever possible I install python packages to anaconda’s interpreter and directories. I use home-brew to install everything else…including boost. In case it helps, I’ve also attached the log file. Any direction would be appreciated. Thanks. Gareth
