libsqlite3-ruby* is the sqlite3-ruby gem (the first one seems to be a 
meta package, once Ubuntu switches to Ruby 1.9 by default, so that 1.9 
versions of gems get pulled by apt-get / synaptic).

libsqlite3-0 and libsqlite3-dev are the plain old C based SQLite3 
binaries and development packages, unrelated to Ruby, unless you build 
the native extension of the gem (which only needs the -dev package, 
technically speaking).
