Latexdiff won't build because of checksum failure; breaks texlive

[rpgoldman]

When I try to build texlive, it triggers building of latexdiff.

Specifically, it tries to download latexdiff-1.1.0_2.darwin_15.noarch.tbz2

port can't find this tarball because the most up-to-date version on the servers (at least the ones that I search) is latexdiff-1.1.0_2.darwin_14.noarch.tbz2

Unable to find the tarball it wants, port falls back to loading latexdiff.zip from CTAN.

After downloading the zipfile, port raises a checksum verification error and crashes.

I'm afraid I'm not sophisticated enough to know:

1. why is it that port wants to load version _15
2. why it falls back from loading a tarball to loading a zipfile
3. where the checksum it's using comes from and why it tries to apply the checksum for a tarball to a zip file.

The exact error transcript is:

I encountered the same behaviour, except on my configuration a different file is to be downloaded: latexdiff-1.1.0_2.darwin_11.noarch.tbz2

I did a totally new installation on a Mac OS 10.7.5. using the .pkg from macports. When trying to install texlive, the installation breaks due to the dependency on latexdiff.

[rpgoldman]

Should have recorded this before: I am running 10.11.2 (El Capitan).

[mojca (Mojca Miklavec)]

I committed r144012. I wanted to switch to GitHub, but the repository there is not quite ready yet.

[rpgoldman]

Thank you; works fine now.

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #50175.

[ars@…]

my build was fixed, too.

This problem is back. This happened a few minutes ago, after I had cleaned latexdiff and tried again:

r144953 is now fetching files from GitHub. I realized that there is a "download" link that's different from the generated files straight from the source tree and that file look ok for now.

[squiggledid]

Still broken, I'm afraid. I just cleaned and tried again, and got exactly the same error:

I don't know the details of how this works, but it seems to me from the log file that nothing was actually fetched. There is 404 message for every URL tried. Here is the log file:

Did you update the ports properly? MacPorts should no longer look for latexdiff.zip.

The new checksums are

checksums           rmd160  51e9e85c8152143a9229b7bd7c41e6f67ef85ecd \
                    sha256  5d772897c77d931ae0a6999f7254ba66a8fe4706d2508fdeebbb5c4ab6ba290c

If MacPorts is checking for anything else, there's something wrong.

[squiggledid]

I did "sudo port clean latexdiff", and then "sudo port upgrade outdated" (which was what I was doing when I first saw the failure). I figured cleaning would be enough, but now realise that I needed to update the port file itself.

I've just done a "sudo port selfupdate", again followed by the steps above. This took a quite a while, as it triggered other (large) ports to update (surprisingly many, as I last did this only a couple of days ago)..

The bottom line is that latexdiff installed without problem this time.

Thanks.

Replying to david.mcg.squire@…:

Sure. Just "sudo port upgrade outdated" without "sudo port selfupdate" (or updating a copy in your local tree if you have one) will never be enough if a problem your reported just got fixed. The large number of other ports could be a coincidence, but you always need to update (at least) the Portfile for port in question.
