Portage should handle transitive dependencies no problem, so my guess |
| 22 |
is that you have your system for a long time, and over the period, |
| 23 |
this is what happened: |
| 24 |
- package-old.version, pulled in dependency-some.version, which |
| 25 |
depends on further-dependency-some.other.version |
| 26 |
- package was upgraded to package-new.version which doesn't depend on |
| 27 |
dependency-some.version anymore |
| 28 |
- you have dependency-some.version on your system, which depends on |
| 29 |
further-dependency-some.other.version, but isn't really reachable by |
| 30 |
the current dependency tree |
| 31 |
- depclean tries to get rid of those, but produces a very scary output |
| 32 |
with seemingly useful packages listed. |
| 33 |
|
| 34 |
I cannot be 100% sure on that, so I recommend you do the following steps |
| 35 |
|
| 36 |
1. make sure USE flags for all your packages are properly set, don't |
| 37 |
use USE=flag emerge package, actually edit /etc/portage/package.use |
| 38 |
2. do a emerge --deep --newuse --update world so that all packages |
| 39 |
pick up the correct USE flags and hence dependent libraries. |
| 40 |
3. emerge -pv depclean, it'll explain what pulled what in. |
| 41 |
4. At this point, it should be safe to emerge depclean to get rid of |
| 42 |
the obsolete dependencies |
| 43 |
5. revdep-rebuild |

| 58 |
looks safe to me. Don't forget a revdep-rebuild after the "emerge -C =gcc-3*" |
