how to install "graph-tool" in UBUNTU 12.04 LTS 32 bits and windows7

Hi, I'm trying to install "graph-tool" in UBUNTU 12.04 LTS 32 bits and
windows7 but I have some problems.
I cant find the method for windows7
and for ubuntu when I make:
apt-get install python-graph-tool

I get something like:
Les paquets suivants contiennent des dépendances non satisfaites :
python-graph-tool : Dépend: libboost-graph1.54.0 mais il n'est pas
installable
                     Dépend: libcgal10 mais il n'est pas installable
E: Impossible de corriger les problèmes, des paquets défectueux sont en mode
« garder en l'état ».

How to solve this please!

Ubuntu 12.04 is not supported. Its versions of Boost and GCC are too
outdated to compile graph-tool. You need to update to a newer Ubuntu
version.

Windows is also not directly supported. You should be able to compile it
with Cigwin, but some people reported some difficulties.

Best,
Tiago
