I'm trying to install the sqlite3 gem for ruby on rails and am getting this error... I've already successfully installed sqlite3 via yum.
Building native extensions. This could take a while...

An older guide shows how to install sqlite and all the devel packages too, plus some other tricks. It looks like you are just messing around with a tutorial, but if you are going to develop, I'd suggest installing a 'real' database. One with more features, and what not. MySQL or PostgreSQL.
Also make sure you are installing it via the 64 bit OS too, as it looks like it needs it from that error stack, or is looking for it.
