Installation newest Qt on Debian Squeeze

I believe that is the right part of this forum.

I am having a problem with installing newest Qt (mean 4.7) on Debian Squeeze, as the newest version in repo seems to be 4.6.X which installing I would like to avoid as I am using 4.7 on Windows (and sometimes develop a little bit on Linux and sometimes on Windows) and I had one issue now when I tried to compile the code written under 4.7 on Debian... some methods for QList seemed to be not introduced.

I tried to install it by using Apt-Pinning (who knows what it is, knows also the problems I encountered), due to the problems with dependencies I abandoned this idea.
Secondly I tried to install from ready-to-use standalone bin file... failed also (bash returned some errors)
Now I would like to install it from source... is there something more I need to know more than already is included in docs
