The problem is that you now have two versions of libdar installed and
the linker is finding the older one (the ubuntu package). 

Go into /usr/lib and 

sudo rm libdar.so



then create two symlinks:

sudo ln -s /usr/local/lib/libdar.so.3

sudo ln -s /usr/local/lib/libdar.so.3 libdar.so



kdar should now compile and run :D



It's well worth the effort - KDar is excellent and I was quite
surprised not to find it in the repository
