Ruby-oci8 2.0 gem does.

In lib/oci8.rb:
  case RUBY_VERSION
  when /^1\.9\.1/
    require 'oci8lib_191'
  when /^1\.8/
    require 'oci8lib_18'
  else
    raise 'unsupported ruby version: ' + RUBY_VERSION
  end

It includes oci8lib_191.so for ruby 1.9.1(*1) compiled by VC6 and
oci8lib_18.so for ruby 1.8(*2).

If a ruby binary gem doesn't work for 1.9, it should set required_ruby_version
in the gemspec correctly as follows:
  s.required_ruby_version = '~> 1.8.0'   # 1.8.0 <=  ruby version  < 1.9.0
