[ gpsdrive ] Another compile error

[Mark Williams]

Hi,

I'm trying to get to try out the Openstreetmap link in this; I 
downloaded from svn, but get this:

map_handler.o: In function `loadmap':
/home/mark/geo/gpsdrive-2.10pre4/src/map_handler.c:664: undefined 
reference to `get_mapnik_imagedata'
collect2: ld returned 1 exit status

 From the archives, I know I can turn off the option to use this; I 
particularly don't wish to do so.

I'm obviously missing something, but I can't see quite what. It compiled 
mapnik.cpp quite happily, which contains said function.

Anyone know what else I need here?

Thanks..
Mark
