Well, Sailfish is Linux, so grabbing the packaged mapnik and its build-deps for Fedora or whatever should just work. As for Android, it's become such a caricature of what Linux should be that I don't have any idea.
I think I'll try to build the Mapnik packages from Open SUSE or Fedora on the Mer OBS.

Even though there are (cross) compilers, it is usually quite a pain to build stuff on Android due to the various quirks and hack inherent to the platform. And another issues is cramming the stuff you have built to your APK in a workable manner due to the lack of dependency handling support.

Overall I think I'll just concentrate on getting one offline map rendering solution going and we will se how to go from that.

This would greatly diminish the amount of file reading and RAM used.
That's basically the plan - storing the OSM geometry corresponding to a tile image in a sqlite tile database. The current tile handling & caching mechanisms could be used, but instead of displaying tile images, the tile geometry would be rendered (using a map style) and then displayed.

That's unfortunately the expected behavior - all these features were planned but I have not managed to implement them before I stopped working on the N9 port of modRana.

Doesn't work on Jolla, I've not recently tried on n900.

Thanks, I'll take a look.

Update:
Should be now fixed!
