That's not output from the above command (dev-python wouldn't be  
there.)  Please show the output of the above eix command, or perhaps  
try "eix-installed -a | grep dev-qt" for another look to be sure all  
are at the same version.

What is trying to pull in qtcore-5.15.0?  You started this with a  
problem of pdf viewers all complaining about mismatched qt versions,  
but this looks like a portage issue.  If you are manually marking  
dev-qt packages as ~, you have to be sure you have gotten them all.   
All dev-qt packages (some, such as qt-creator are on a different number  
scheme) must have the same version.  They are generally released all at  
the same time, so incomplete upgrades are likely due to a problem in  
package.accepted_keywords.
