When building graphviz without allowing fallback to FreeBSD's distfile cache the build fails during the fetch stage [1] (i.e. upstream is no longer serving up the source files). It seems the source location has been changed to https://graphviz.gitlab.io/pub/graphviz/stable/SOURCES/graphviz.tar.gz [1] http://dbn.westeurope.cloudapp.azure.com/10_4-i386-default-soundkonverter/2018-09-13_01h53m13s/logs/errors/graphviz-2.40.1_6.log
