Everything above this line is fascinating but completely unrelated to your

Read it backwards from the bottom up. It means that cryptsetup requires
device-mapper (a version greater than 1.00.07-r1) and portage has chosen
device-mapper-1.02.24-r1

Same as above, except that both kdelibs and kdebase-meta have pulled in
kdebase-data. Sometimes the list of package that pull in other gets very long
and the list might be truncated with a message something like "plus 33
others..."

It's just a statement that something will be merged, followed by the packages
that caused it to be merged. It's all usually of the form
"exact package" pulled in by
"package spec from an ebuild"
pulled in by
"something else"
Apparently you have konqueror-akregator in world (nothing else is pulling it
in) which causes akregator to be merged. You must remove konqueror-akregator
manually using
emerge -C konqueror-akregator

You don't have a conflict per the above.
Actually, you removed the relevant part of the output and didn't post it, so
now we can't help you.
Please repost the full output.
When you identify the blocker, you have to ask yourself some intelligent
questions, like:
portage wants to merge packages A and B, but the ebuilds say that A and B
cannot be installed together. What is pulling in A and what is pulling in B,
and why? It might be a hard dependency, it might be a USE flag issue, it might
be that the package is in world. Also learn how to read ebuilds

Not the foggiest idea - you removed the info that tells me that :-)

First get rid of KDE-3.5 completely, then install KDE-4:
Inspect you world file and unmerge everything related the KDE-3.5. Then run a
--depclean o remove dependencies not in world, then run emerge -uND world and
double check that nothing kde-3.5 related is pulled in. Rinse and repeat till
this is true.
Then merge KDE-4 as usual

Before anyone explains to you how to drive gentoo, you should help yourself
first:
1. Re-read the install document. All of it. Maybe read it three times.
2. Read the man pages, all of them, several times. You can find this list
with"equery files portage" and looking for files under "/usr/share/man"
There is no easy way through this, you have to understand how portage and it's
builds work and that involves study on your part.
