No, that is incorrect and your reading of the output is wrong.
Emerge detects blockers by looking at what is currently on the machine or what
it wants to install and seeing if that will block with what is on the machine
or what will be installed.
You do not have to have a package installed to create a block - it can be
caused by something that is due to be emerged (and hence will only be
installed in the future).
Look at the second blocker line. It says:
<=x11-libs/qt-4.4.0_alpha:4
That means:
- a version in SLOT 4
- the version number is less than 4.4.0_alpha is blocking/blocked by qt-4.4.2
You do not have such a package installed. That's cool.
You need to find out why portage thinks it must install such a thing. That's
why I asked you for emerge -t earlier. Find an entry for
<=x11-libs/qt-4.4.0_alpha:4 in that list and look above it to see what pulled
it in. Fix that thing and portage will stop trying to pull in an old version
of qt and your problem will go away.
I earnestly recommend you do not go through a full reinstall. That will teach
you nothing. You need to go through this at least once to learn how to deal
with it, it's a necessary gentoo skill
