Yeah, this situation is similar to backporting.

If you are unable to workaround the freetype bug in navit or use an
older version of navit that works with that version of freetype, then
try this:

Since the ABI is the same for both versions of freetype, I would
suggest introducing a libfreetype6-navit package that contains the
newer freetype library in a private directory and adding an rpath to
navit pointing at that directory:


This is better than static linking since you can upgrade
libfreetype6-navit separately to navit.

In addition the freesmartphone.org distribution SHR (based on
OpenEmbedded) has a port to the N900 (in the early stages):


There is also an Android port:
