rb_require( "relative/path/to/raliasfile" );

My preference is relative paths. Eventually you'll want to release
this as a gem to other developers, and they might not have the exact
some directory structure that you do.

VALUE alias = rb_class_new_instance( 1, args, RAliasFile );

Where 1 is the number of arguments in the args array, args is the
array of arguments (as a VALUE*), and RAliasFile is a reference to the
class you would like to create.

Unless you need separate modules, I would flatten your directory tree
-- i.e. consolidate all the files in your ext/lib folder up into the
ext folder.

Hope these were helpful suggestions.
