Main Log

[ryandesign (Ryan Carsten Schmidt)]

The developers of graphviz seem to be having some trouble with their server. They haven't posted a new source download since 20150520 (they usually post them every 24 hours), and now somehow they've replaced the 20150520 file with a file whose contents were modified on 20150524. I'll ask the graphviz developers what's up. In the mean time, you can download ​the correct file from our server. See ProblemHotlist#fetch-failures for further instructions.

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #47956.

I've discussed this with the Graphviz developers on their mailing list: ​http://lists.research.att.com/pipermail/graphviz-interest/2015q2/007893.html

They changed how they're packaging the development versions. They used to package a new version every 24 hours regardless if anything changed; now they only package a version if the source has actually changed. But until the 24th they were inadvertently repackaging the same version every day, which caused the checksums to change each time, because some files in the archive have the timestamp of when the archive was made. Their packaging script has been fixed and this won't happen for future versions.

This will resolve itself next time graphviz-devel is updated, but until then I worked around it in r137091. Please wait 30 minutes, then run:

sudo port clean --all graphviz-devel
sudo port selfupdate

Then it should work.
