By default, graphviz will look for the presence of Qt4 and will build --with-qt if Qt4 is found. As a result, it will fail to build when qt4 libraries are present. I have a critical requirement for qt4, so will not be deleting it until that requirement is resolved.
Those who still need qt4 and/or have not deleted it can't install graphviz-2.40.1_8. This may be fixed either by patching the configure script to default to "--with-qt=no" or by adding CONFIGURE_ARGS+= --with-qt=no to Makefile.
Thanks the Qt4 removal from r496028 broke it.
