I am the developer of that theme. Unfortunately, my N900 has been non-functional for a while now, and I haven't had the time to try and fix it (what with the end of school and everything). That being over now, I should finally get a chance to try to update the theme to be compatible with the new theming system. I didn't realize modRana could be installed on a regular Linux system - martinK, where can I download it from? This would allow me to work on the theme on my computer until I get my phone fixed.
