Anyone accepting credit cards in Ruby on Rails?

Has anyone here successfully accepted credit card with a “Ruby on Rails” setup? The best thing I can find is ELC’s Ruby on Rails Paypal plugin.

I am able to run it in my local environment, but when I try to run it on Dreamhost’s servers, it doesn’t work because “soap4r” need to be installed. This is a ruby library by the way.

Has anyone ever gotten ruby libraries successfully installed under rails?

I hesitate to accept (and store) credit card info locally. PCI 6.6 requires you have your code professionally audited if you engage in credit card transactions.

3rd party gateways (like PayPal) carry the burden instead of the individual.
