After installing REE, it should just be a case of:

  yum install sqlite-devel
  gem install sqlite3-ruby

(assuming you have the compilers installed). So if that fails, what 
error message do you see? It should be possible to resolve it.

Beware: ruby 1.9.1 is not the small incremental change that you would 
expect from a "minor" version bump. It has a completely different 
execution engine (YARV) and in many ways is a completely different 
language, such as completely new behaviour for the String core class.

Not all 3rd-party libraries have been updated to work with both 1.8 and 
1.9, although many now have. Note that Rails 3 beta is reputed to crash 
ruby 1.9.1, but runs with the not-yet-released 1.9.2.

On the other hand, REE is based on the mature 1.8.7 codebase, tweaked 
for improved memory usage. This is a more conservative choice.

If you still end up building ruby from source, don't forget that you 
could build either 1.8.7 or 1.9.1 (or a 1.9.2 preview).
