I have no clue how to build a .deb or .rpm package yet, so it’s just a .zip for now.
Though I have it working on my own Ubuntu 9 machine, I haven’t the faintest idea whether the client will run on other Linux boxen. At the very least, you’ll probably need to have the wxWidgets 2.8 libraries installed to run the client on Linux. I suppose at some point I’ll figure out how to build installer packages.
Version 0.14 of the client for Linux is now available for download. Hopefully there’s someone who can try it and let me know the result. In this case, it’ll probably be “I had to add libraries X and Y and Z before it would run”. Then again, since wxWidgets is so widely used on Linux (VLC, Audacity, etc), chances are good that most people will already have the necessary pieces installed.
