#50174: Latexdiff won't build because of checksum failure; breaks texlive
-------------------------+--------------------------------
 Reporter:  rpgoldman@…  |      Owner:  macports-tickets@…
     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.3.4
 Keywords:               |       Port:  latexdiff
-------------------------+--------------------------------
 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 will attach the logfile.
