This shows that 3.5.1 is available, but is masked by a ~arch keyword. 
This means that the ebuild for 3.5.1 is not stable yet, and is not 
guaranteed to work (though it most likely will).

Same for eclipse-ecj...

Here, he shows what would be installed if you ran "emerge elipse-ecj".

This is what would happen if you temporarily told the system to allow 
the installation of ~arch packages. Temporarily setting ~arch is a Bad Idea!

That is because the newer version is keyworded with ~arch. Emerge will 
not tell you that there is a newer, keyworded version available.

Don't worry, I'll show you how in a little bit!

As far as I know of, that is not possible without ugly hacks.

I don't know what you mean by "must I?", but the answer to "How do I?" 
is right here:
First, you need to create a folder called /etc/portage as root. Then, 
create a file called package.keywords in that directory. When you want 
to install a keyworded package (dev-java/eclipse-ecj-3.5.1 in this 
case), you run

ACCEPT_KEYWORDS="~x86" emerge -pv eclipse-ecj

to see what packages are needed for the keyworded version. Then, you 
copy the the package names mentioned to package.keywords. In the example 
above, the command outputted:

[ebuild  N    ] dev-python/pyxml-0.8.4-r2  USE="-doc -examples" 0 kB
[ebuild  N    ] dev-java/javatoolkit-0.3.0-r3  17 kB
[ebuild  N    ] dev-java/ant-core-1.7.1-r4  USE="-doc -source" 6,828 kB
[ebuild  N    ] app-admin/eselect-ecj-0.3  0 kB
[ebuild  N    ] dev-java/eclipse-ecj-3.5.1  USE="ant" 1,268 kB
[ebuild  N    ] dev-java/ant-eclipse-ecj-3.5.1  0 kB

So you would add this:

dev-python/pyxml-0.8.4-r2
dev-java/javatoolkit-0.3.0-r3
dev-java/ant-core-1.7.1-r4
app-admin/eselect-ecj-0.3
dev-java/eclipse-ecj-3.5.1
dev-java/ant-eclipse-ecj-3.5.1

to the package.keywords file (note that this will probably be different 
for your system, you should run the command yourself and use that output 
to find out what you should put in the file). I would also put a note 
above the lines to say why and when they were added, in case I forget.

Then you can run "emerge -av eclipse-ecj" and see if it lists the new 
versions of everything.
