This is quite correct. Having multiple versions of a package installed |
| 16 |
is often necessary. This is the case. Some of your programs require qt3 |
| 17 |
to function, others require qt4. There are applications not prepared |
| 18 |
for qt4 at all. When you unmerged one of the qt's, you probably disposed |
| 19 |
some package(s) of their dependency, so emerge -uD promptly re-emerges |
| 20 |
the now-missing qt. |
| 21 |
|
| 22 |
The [ R ] flag means an already-installed package was to be re-emerged. |
| 23 |
Then you unmerged one such package and [ R ] became [NS ], which means |
| 24 |
a not-yet-installed package version is about to me emerged. Both qt and |
| 25 |
gnupg are "slotted" packages here - meaning it's possible to have |
| 26 |
multiple versions installed at the same time. Slotted - that's the "S" |
| 27 |
tag in [NS ]. |
| 28 |
|
| 29 |
So by and large, the right thing to do here is let emerge -NDpvu do |
| 30 |
what it wishes to do and keep both versions of both packages. If you |
| 31 |
want as many applications as possible to use qt4, adding the "qt4" USE |
| 32 |
flag may help. May or may not. I don't know what exactly this flag does |
| 33 |
in all those ebuilds using it. |
