uhm.. redland-config was not in my path (i located it in 
/usr/redland/bin/redland-config); now i linked from /usr/bin and it reports

attilio at attilaptop:~/svn/redland/bindings$ redland-config --swig
/usr/redland/share/redland/Redland.i

i then re-checked out from SVN, reconfigured as before, ran make and got

still i cannot get them to compile: got any idea by looking at the above 
make output log?
