Shameless plug:

My Nice-FFI library <http://github.com/jacius/nice-ffi/> has code to
do exactly what you want. Have a look at the usage guide and see if
you're interested:

  http://github.com/jacius/nice-ffi/blob/master/docs/usage.rdoc

Be aware, the API for Nice-FFI is not considered stable yet, i.e. I
might change stuff in the future (although in practice it doesn't
change much). But all the code is under the MIT License, so you could
package it (or parts of it) with your code if API changes concern you.
