I never faced this problem myself and I can't assure this will solve it but
having seen other similar problems, I'd start by checking that your system
has the 'libsqlite3-dev' package installed.
Anyway its probably better to install mysql or other db system, as you will
do it eventually anyway. Just make sure you install the '-dev' packages as
well.
Regards.
