On a sane system, if qt3 is no longer needed you could clean it with |
| 13 |
emerge --depclean --ask. That should in fact clean anything that's not in world |
| 14 |
and is not a dependency (might it be directly or indirectly) of a package in |
| 15 |
world. |
| 16 |
|
| 17 |
If emerge --depclean --ask doesn't report it on the output list, then there's |
| 18 |
something depending on qt3 installed. |

Remember that setting USE="-qt3" doesn't magically remove the dependency on |
| 21 |
qt3 for those programs that needs qt3. Kde 3.x relies in qt3, and no USE flag |
| 22 |
can change that. USE flags only change optional settings, for kde 3.x qt3 is |
| 23 |
not an option. |

However, most people don't usually care about sanity, and in that case, you |
| 26 |
should be careful when using --depclean. |
