I’m working out of the book RailSpace, and when I installed it, it  
installed Mongrel, but apparently not SQLLite, and I recieved this  
error message:

no such file to load – sqlite3

then, you just need to install SQLite3 - search up to find a guide for  
your OS. It’s quite simple. You will also need to install the  
appropriate Ruby gem for it.
