Hi Jay,
I'm the project maintainer but haven't done much development on Ruport itself.
Prawn and Ruby 1.9 support are the two main issues but no one has
submitted any patches for it (with one exception) and I haven't required the use of Ruport
for any of my projects in a long time so I have little reason to work on
it. I should probably be on top of things a bit more, especially the FasterCSV issue.
A Ruport Formatter isn't actually designed to do that much work and there is a basic PrawnPDF class written by Michael Pope. I think Prawn (but haven't had time to research) probably supports most of what the old PDF formatter did.
I'm happy to accept patches and they will usually be merged within a short time. I'm also available for support questions.
I hope that answers your questions.
Best regards,
Andrew
