Was able to fix this by first doing: sudo port install libffi
Once that was installed I was able to do:
gem install selenium-webdriver
gem install watir-webdriver --pre
However when I try to run my scripts I get the following error:
/opt/local/lib/ruby/gems/1.8/gems/safariwatir-0.3.7/lib/watir/
exceptions.rb:12: superclass mismatch for class UnknownObjectException

I comment out safariwatir in my require section and rerun my tests and
get:

Anyone know what might be causing the and how to fix?
Thanks.
