Thanks.

It's funny.
I just succeeded to install kdelibs4-trinity-dev by downgrading libtiff4 to 3.8.2-11.5.

For a moment, I had:
kdelibs4-trinity-dev 4:3.5.13-0debian9+r1261449+pr12~squeeze  from trinity/squeeze
libtiff4-dev         3.8.2-11.5                               from lenny
libjpeg62-dev        6b1-2                                    from wheezy

But now I have your versions.
My problem is that Debian is replacing libjpeg62 by libjpeg8 in wheezy.
(http://bugs.debian.org/640089)
(And "apt-get dist-upgrade" will suppress kdelibs4-trinity-dev, libarts1-trinity-dev
and libqt3-mt-dev.)
