Ok, so, here's the status:

I changed pyRadio to PySide from v4 and up. It was fully functional on the last release of MeeGo that I tried. I never built an RPM for it for MeeGo but made sure it worked and played.

Harmattan is a hybrid. It uses a MeeGo-like core but with the Deb system. rm_you said here that he would maintain a harmattan port and posted a deb for harmattan at his link. However, that looks to have never been updated since 3.6.1.

I do not own a N9 or an N950. I will not pay $700 for a device without a keyboard, not to mention I currently have disagreements with Nokia as a whole because of their drop of support for these devices. So I cannot test it.. however.. if someone wants to grab the deb from Fremantle and try to install it and report back any errors to me I will be more than happy to help someone get this working on Harmattan.

I have no idea how to publish or host a deb in whatever 'official' repo the harmattan devices use. So, if/once we get this working on harmattan (if it doesn't already), the only way to get it will be to download the deb directly and install either via a terminal or if the built-in package manager lets you install from files you can do that too.

ETA: Btw, pyRadio is currently broke and I am working on it so you can grab the current 4.1 deb and see if you get any errors installing or running it.. but it won't completely work right now. If you want to know when it's fixed, follow the official thread.
