Comment (by jmroot):

 If it's all ports and not just this one, then most likely your
 configuration is not compatible with the build server's. See the second-
 last bullet point in wiki:FAQ#fromsource.

 If clang-7.0 is in a separate ports tree, then it could be the same
 situation as #59463 (which is really a feature, not a bug). If you know
 it's safe to use the official archive sites with a custom ports tree, you
 can copy `_resources/port1.0/fetch/archive_sites.tcl` from the official
 ports tree to the custom one, as Rainer mentioned in the other ticket.
