You might have seen this one coming: gPodder is already working on Sailfish OS. If you want to try it out in the emulator yourself (no MP3 playback due to missing codecs, and some parts of the UI have not yet been ported), install the Sailfish SDK and start the emulator (thanks to the interpreted'ness of Python, we don't have to care about cross-compiling at this point). Then, SSH into the emulator as user "nemo" (I'm purposefully vague here - if you can't figure out how to SSH into the emulator, then you probably shouldn't be trying it out at this point).
From the "nemo" user, become root (use "su -", root password is "nemo") and then install some dependencies:
zypper in python-pyside git qt-components
With that in place, go back to the "nemo" user and get gPodder from Git:
git clone git://github.com/gpodder/gpodder.git
Then, cd into the Git checkout and start it as usual:
Again, you don't have to do any installation or compilation steps for gPodder - it will work straight out of a Git checkout (that's how I use it all the time). If you "export" the Emulator as appliance in VirtualBox and then "import" it on a different machine, you can even work with this nicely on Mac OS X and Windows. The fact that the emulator is just another Mer installation also means that you can install a compiler and -devel packages for quick development and testing. Vim 7.3 is already installed, I only wish zsh was also available in the Mer repos :)
