GMTA. :)

I'm sensitive to the issue of this being build time reliant which means
that if the user upgrades their ruby version the rc.d script could
become outdated. I think that this could be ameliorated by forcing the
shebang line to be just /usr/local/bin/ruby, but I'm not sure how ruby
handles that.

One way we could improve the situation would be to support a glob
pattern for command_interpreter. Haven't thought through the
implications of that though.
