You can get old ebuilds from http://sources.gentoo.org, and maybe take whole portage tree snapshot from a given point in time (never tried it). Or maybe there are portage webrsync snapshots going back (again, never used them). If you have demerge installed it should have taken snapshots of which packages you had installed at each time you ran emerge as well. I think that'll still depend on those old versions still being in the tree, which for security fixes etc they usually are not kept, but all should be on http://sources.gentoo.org
