Error: org.macports.build for port graphviz returned: command execution failed
The fact that it went straight to building graphviz, skipping the earlier phases fetch, extract, patch and configure, shows that this was not a clean attempt. If you were still experiencing the problem, we would ask you to "sudo port clean graphviz" and try again. If that then worked, then I would say you had experienced #29223, which will be fixed in a future version of MacPorts.
Error: Failed to install graphviz
Please see the log file for port graphviz for details:
/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_graphics_graphviz/graphviz/main.log
We would need to have seen the contents of this log file to know what went wrong. But since you've already tried again, the original log will have been overwritten. And if you've been able to successfully install graphviz, then the new log will have been deleted already (unless you had previously set "keeplogs yes" in macports.conf; the default is not to keep logs of successful builds).
I decided to install "graphviz" directly, and then it worked:
Great, then there's nothing to do here.
