You can get old ebuilds from http://sources.gentoo.org, and maybe take |
| 23 |
whole portage tree snapshot from a given point in time (never tried |
| 24 |
it). Or maybe there are portage webrsync snapshots going back (again, |
| 25 |
never used them). |
| 26 |
|
| 27 |
If you have demerge installed it should have taken snapshots of which |
| 28 |
packages you had installed at each time you ran emerge as well. I |
| 29 |
think that'll still depend on those old versions still being in the |
| 30 |
tree, which for security fixes etc they usually are not kept, but all |
| 31 |
should be on http://sources.gentoo.org |
