Arch Linux

I want to replace "qt-enhanced" (kdemod repository) package with the regular "qt". They both provide the same functionality so I thought there would be no problem. Pacman says:

:: qt conflicts with qt-enhanced. Remove qt-enhanced? [Y/n]

Y, that's exactly what I want to do. But then:

error: failed to prepare transaction (could not satisfy dependencies)
:: qt-enhanced requires dbus-qt3
:: qt-enhanced requires skype
:: qt-enhanced requires smplayer
:: qt-enhanced requires dssi
:: qt-enhanced requires qjackctl
:: qt-enhanced requires arts
:: qt-enhanced requires kdelibs
:: qt-enhanced requires qscintilla
:: qt-enhanced requires qca
:: qt-enhanced requires qca-tls

IMHO it should be possible to change a library version without uninstalling and then installing back all the packages that depend on it (After all, it's not Gentoo, is it?).

Btw. I think it should say "required by" instead of "requires" in the error message. When I do "pacman -R qt-enhanced" manually, the error message is:
