Those instructions are for updating the source package.  As RSQLite 
always uses the version of SQLite included in its sources, installing 
another version will not help!  You need to update the source package 
and then install it (which inter alia involves compiling the SQLite it 

The current sources are


and those instructions are not right, as that needs to be extracted to 
RSQLite/src/sqlite, not RSQLite/src .

You can use something like

curl -O http://www.sqlite.org/2015/sqlite-amalgamation-3081101.zip
tar xvf .../RSQLite_1.0.0.tar.gz
pushd RSQLite/src/sqlite
unzip -j ../../../sqlite-amalgamation-3081101.zip
rm shell.c

Works for me ....
