I found some time to update the preliminary OS2008 port to version 2.1.1 today, the package and the patches are available under http://people.debian.org/~tschmidt/m.../maemo-mapper/ as usual.

My suggestion to OS2008-users is to stick with version 2.0.5chinook5 from my page, because of the GPS-related problems described in the last posts.
(The only way i can use GPS with maemo-mapper 2.1.1 on my N800 in an easy way is to activate gpsd with the wayfinder app or with the gps control panel applet and setting up maemo-mapper to use the gpsd on localhost, port 2947.

@Gnuite: Regarding the patches: I had to revert the check for libgdbm to the way it was done in mm 2.0.5 because otherwise libgdbm was not found.
Another other issue was that MSGFMT and GMSGFMT variables were empty, so it was not possible to build the locales (i did specify them with AC_PATH_PROG as a workaround).
The most noticable difference to the previous port is that i disabled displaying of the stopwatch because i was not able to fix the problem with it not being showed correctly.
