I tested it again and for me it works. In the patch a Makefile.am is
changed. So you need to do "make -f Makefile.cvs" after applying the
patch. After running "configure" the file src/Makefile should contain
"emotnode.cpp". Now building and running should work without problems.
I attach the patch to this mail again because I corrected the spelling
of smiley and smileys.
