installing lazarus from debian backports - Broken package

[Csanyi Pal <csanyipal@gmail.com>]

Hi,

I setup source.list for the debian backports:

deb http://www.backports.org/debian etch-backports main contrib\
non-free
deb http://www.hu.freepascal.org/lazarus/ lazarus-stable universe

and want to install lazarus-ide

I have installed fpc, fpc-source, fp-compiler, fp-ide, fp-units-base,
..., fp-utils, all these are versions 2.2.2-3.

When I try to install lazarus 0.9.26-0, I get error messages:
