I use 2.2.14 on both hosts (and usually latest ~x86 portage is |
| 42 |
there). I thought that running fixpackages should be enough to run |
| 43 |
emerge with --dynamic-deps=n. |
| 44 |
|
| 45 |
I'm afraid I will not be able to run emerge @changed-deps prior to |
| 46 |
@world update due to too old packages installed (e.g. versions not |
| 47 |
in tree anymore), blockers and unsatisfied deps. |
| 48 |
|
| 49 |
When I'll manage to run emerge -DNupv @world without errors, I'll |
| 50 |
send you stats for both runs with and without dynamic deps. |
| 51 |
|
| 52 |
By the way, do you need pstats files (e.g. for some extra data) or |
| 53 |
pdf graphs are sufficient? |
