This is not so important I think.

Hmmm.. I use Ubuntu which is Debian based and uses the same system more
or less for "apt-get"ing packages. If not all, most of these stuff
should be easy to install in Debian.

How? 

I am not so sure ;-)

Maybe the "Debian & GIS"  [1] page helps a bit more

I am also a beginner in all this. But I think I had some similar problem
once... maybe you need to locate where the sqlite3 files are (maybe the
libsqlite3??? files) and do something like the following described in a
post [1]

" >5 In order to run GDAL after installing it is necessary for the
shared
library to be findable. This can often be accomplished by setting
LD_LIBRARY_PATH to >include /usr/local/lib. On Linux, you can
add /usr/local/lib (or whatever path you used for installing GDAL)
to /etc/ld.so.conf and run ldconfig as root. "

I also needed to add some lines in my /etc/ld.so.conf when compiling/installing from source some stuff.

I don't know if it's identical in Debian.

Best Luck!
