[gentoo-user] complex depencies - how to cut the Gordian knot?

[gentoo-user] complex depencies - how to cut the Gordian knot?

[Helmut Jarausch]

Hi,

I'm upgrading Gentoo nearly each day for 2 years now. 
But once in a while I'm lost, like this time

emerge --keep-going -j2 -1 --ask --update --newuse --deep @system @world
gives a lot of blockings which I don't quite understand (and there are
so many) - see below.

I'd be very grateful to some hint how to proceed in such a case.
I've already looked at the dependencies of some of these packages
but I can't find the reason for those blockings.

(I'm using portage 2.2_rc33)

Many thanks for your help,
Helmut.

You have a mixture of qt-4.5.1 and 4.5.2 packages there. 

Do you perhaps have x11-libs/qt installed? Unmerge it, it's a meta package and 
you don't need it. Let other apps that use qt pull in the necessary packages.

Yes, there is something strange about the qt packages that triggers
this problem.  It looks horrible but the solution is just to remove
all of the qt packages manually before doing your update.  Dunno why.

All these version -4.5.1-r9999 packages look very suspicious to me.  
Honestly, I'd uninstall all the the blocking packages, `emerge -upv  
world` and let suitable versions be pulled in as dependencies.

Stroller.

Yes, thanks, that was the culprit.

Thanks to all who helped me,

Helmut.
