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