You have to create an overlay for it, see
http://gentoo-wiki.com/HOWTO_Installing_3rd_Party_Ebuilds for more
information.

In this manual you have to create an additional portage tree where you
can put external ebuilds.
I have mine in my overlay folder under media-video/ttcut.
To use the ebuild you have to digest it. Go to the folder where you
have your ebuild.
Then execute "ebuild ttcut-0.11.2_alpha.ebuild digest" without the
quotes, if you do so, some other files are created. One for instance
is for veryfing the the size of source package and so on.
After that you can emerge it as normal with "emerge ttcut". I have
cleaned up the ebuild a bit, so that there are no additional files
needed. You have to download it again at bugs.gentoo.org. Your system
will not be messed up this ebuild installs only two binary files into
/usr/bin one is called ttcut the other ttmpeg. To use ttcut just type
"ttcut" at the commandline and a nice gui opens similar to cuttermaran
the well known cutting tool for windows!

Nothing is wrong with your system qt-4.1.2 is masked by ~x86 keyword
means it is unstable(testing). You can emerge it if you add
"x11-libs/qt ~x86" to the file /etc/portage/package.keywords
