I don't see any errors in that output.  "[blocks b]" means "While there is a blocker here (and I'm
telling you about it), I already know how to fix it." (In this case, by upgrading both libraries
at the same time).  This is purely informative, as can be seen by the fact that Portage lets you
continue.  The time you have to deal with an issue is if you get "[blocks B]" (note the capital
'B'), which means Portage *couldn't* fix the issue for you.
