Wild guesses, semi-tested on amd64 only:

- in the current qtiplot-0.8.5-qmake.patch replace "-lqwt" with "-l:libqwt.so.4"
- check that you have qt:3 built with USE="opengl"
(- gcc-4.3 patching, which were a sort of a detour since I just didn't
want to downgrade gcc in the chroot in which I made my testing in)

After that I got qtiplot-0.8.5 emerged in a simplistic chrooted amd64
environment, which had little more than the basic qt stuff and
explicitly emerged qwt 4 and 5:

 x11-libs/qwt
    selected: 4.2.0-r3 5.0.2-r1

However, I don't know this piece of software and I don't think I'm
going to learn it right now, so that's as far as I planned on
"testing" it right now. :)

Maybe you would like to file a bug in b.g.o? I can dump my crude,
couple-line patches/changes there and whoever needs/maintains qtiplot
can then refine them or reject them as needed.
