libqt4-dev [squeeze]: Package has unmet dependencies?

Hi all,

I'm trying to install 'libqt4-dev' in a squeeze-gripped system, but the installation 
fails with:

The following packages have unmet dependencies:
  libqt4-dev : Depends: libqt4-multimedia (= 4:4.6.3-4em1) but it is not installable
E: Broken packages

Can you please give me a hint for fixing this issue? Thanks in advance.

Btw, as far I see, 'libqt4-dev' is broken by squeeze but not by sid.


Regards,


Luis
