Install lrdf

When I run ‘make’ for lrdf, I get an error message;
gcc -shared .libs/lrdf.o .libs/lrdf_multi.o .libs/md5.o -L/usr/local/lib -lraptor -Wl, -soname -Wl. liblrdf.so.2 -o .libs/liblrdf.so.2.0.0
usr/bin/ld: cannot find -lraptor

raptor is installed

Try to do:
ln -s /usr/lib/libraptor.so.x.x /usr/lib/libraptor.so

Where libraptor.so.x.x is the name of your currently installed library
then redo the make

jop,
problem solved
Thanks much
