Here's the current state of Miro on Gutsy:
we don't have a Gutsy package of Miro for 0.9.9.1 (the current release)
Gutsy does work with what will become Miro 0.9.9.9 (the very soon-to-be released release)
The first Miro version we plan on supporting for Gutsy is 0.9.9.9 which will be released soon--probably in the next week if all goes well. We have been testing with Gutsy over the last month and we have instructions for building Miro on Gutsy in Trac. I want to emphasize that Miro 0.9.9.9 will work nicely on Gutsy and the primary issue here is a packaging one.
The Gutsy universe repository has a Miro 0.9.8 package in it. I've tested it on my Gutsy box and it works for me, however it's missing a lot of the fixes that we've made for 0.9.9.9 which should alleviate problems with Miro and specific video cards. So if it works for you, then that's great, but if it doesn't, then you're going to have to wait until 0.9.9.9.
I plan on making a pass through Bugzilla and make sure any outstanding Gutsy issues are resolved. Additionally, I'll take a pass through LaunchPad and make sure we catch any bugs that didn't get reported upstream to us.
We'll be tagging our repository for 0.9.9.9 rc1 soon--hopefully today and have an rc1 out by tomorrow for Windows and Mac OSX. We'll get a Gutsy rc1 out as soon as we can, but it'll probably take a few days.
If you want to help out with testing rc1, let me know and I'll be sure to point you in the right direction and/or watch the Miro Testing blog.
If you have any problems, please write up a bug in
Bugzilla, comment on an existing bug
with additional information, and/or hop on
irc.freenode.net and let us know.
If you have any thoughts, please comment here and if the plan changes at all, I'll post an update.
As an aside, Gutsy is a great Ubuntu release--I'm running it on one of my machines already and look forward to upgrading my other machine.
