I have a weird problem. I have an ebuild where either qt4 or qt5 can be
enabled. They are both disabled by default and I have to choose which
one I want. The ebuild does that with:
IUSE="qt4 qt5"
REQUIRED_USE="^^ ( qt4 qt5 )"
I'm on the plasma profile which enabled qt5 automatically. However,
portage complains:
The following REQUIRED_USE flag constraints are unsatisfied:
exactly-one-of ( qt4 qt5 )
The qt4 USE flag is enabled. I can't see where. I didn't enable it
anywhere in any of my /etc/portage/* files. If I emerge with:
USE="-qt4" emerge package
then it works. So I have to explicitly disable the qt4 USE flag even
though I didn't enable it in the first place.
Can someone enlighten me?
