I tried to install the newer version or to use cmake, but it didnt work.
I busy this days, so there isnt lot of time to go deeper in it. But I

I added the deb line (deb http://debian.gfoss.it/ lenny main)in my 
sources list, but running apt-get update I get:

Trying to install qgis I get

apt-get install qgis

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
   qgis: Depends: libc6 (>= 2.7-1) but 2.3.6.ds1-13etch5 is to be installed
