To do this, Gentoo has a carefully authored database containing those relations. In this paper, we extract the Gentoo package dependency graph and its changes over time. The final dependency graph spans 15 thousand open source projects and 80 thousand dependency relations. Furthermore, the development of this graph is tracked over time from the beginning of the Gentoo project in 2000 to the first quarter of 2012, with monthly resolution. We perform a cluster analyses of the package dependency graph that reveal meaningful relations among packages, and in a separate paper we analyse changes in the dependencies over time to get insights in the innovation dynamics of open source software. The resulting dataset provides many opportunities for both research on Open Source as well as practice." The research paper is going to be presented in the 11th Working Conference on Mining Software Repositories[2].
