Let me help you with that.



Portage output often gives you "slot conflicts" plus a crapton of 

console output obviously designed by narcissist graving attention (there 

is so MUCH of it, all decorated with alarming !! and ** and whatnot). 

Everyone agrees it must be changed but no-one is prepared to do the 

work. So we learn to live with it.



Blockers never appear in that output. A blocker is a blocker if it shows 

up in the list of stuff t be merged prefixed with

[     B] or

[     b]



All that later stuff is portage telling you (via a core dump....) WHY it 

did what it did. It's full of junk too :-) SO what does it actually tell 

you? Well, making up some version names to make the point clear:



I need to install okular

  because kde is in world

    I can choose SLOT 4 or 5

      5 is preferred because it is latest

        but I can't go to 5 because of something with kde-libs

          [huge dump of output supposed to make the reason for decision 

before this one clearer]

            therefore you are getting okular-16.08.3



And that's about as far as thinking in a general template fashion is 

ever going to get you, especially when portage's decisions involve your 

choice of USE.



When that happens, you have to read all of it, line by line, carefully, 

twice. Or thrice. And then it makes sense.



Try it some time. Work through every line of that output, open the 

relevant ebuild for each and study what is in it. See why portage mad 

that decision, and move onto the next line.



It all eventually makes some form of sense.



And yes, it is way more info that it should be, leaving you only two 

choices:

- don't fix it, but learn to read it

- decide to fix it, do so, commit the patch, and be everyone's hero
