[Tracker] not able to compile branch Turtle

["Stijn Gysemans" <stijn gysemans gmail com>]

I wanted to compile the Turtle branch but it gave me the following error during MAKE.

ib/glib-2.0/include    -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include      -g -O2 -MT tracker-backup.o -MD -MP -MF ".deps/tracker-backup.Tpo" -c -o tracker-backup.o tracker-backup.c; \
    then mv -f ".deps/tracker-backup.Tpo" ".deps/tracker-backup.Po"; else rm -f ".deps/tracker-backup.Tpo"; exit 1; fi
tracker-backup.c:28:20: error: raptor.h: No such file or directory
