For quite some time I've been using the Maemo Autobuilder to create deb packages and those go directly to Extras Devel, from where I expect most people get their software nowadays. And I'm afraid I'm no longer setup to create correct Maemo-style deb files locally - that's why I want to test modRana at least bit before submitting a new build to autobuilder.

On the other hand, you can just grab the latest tarball:
http://modrana.org/tarballs/modrana/...-0.54.5.tar.gz

Unpack it and then run modrana.py from the resulting directory - it should detect it's running on the N900 and behave accordingly. If you can help test modRana like this it would be really helpful! Don't hesitate to report any weird behavior, crashes, etc. And thanks in advance!
