Ken Cunningham told me to look at port distfiles (never thought of that).
the genarated url would be https://github.com/snabb/downtimed/archive/1.0/downtimed-1.0.tar.gz <https://github.com/snabb/downtimed/archive/1.0/downtimed-1.0.tar.gz> and that would cause the 404
he told me to remove github.tarball_from archive, but that failed too.
i should look into /opt/macports-ports/_resources/port1.0/group/github-1.0.tcl

but that results in https://github.com/snabb/downtimed/archive/version-1.0/downtimed-1.0.tar.gz (the version number in 2 places).

i tried some variants of distname and tried

github.setup        snabb downtimed 1.0
distname            version-${version}
master_sites        ${homepage}/archive

and that works. it this acceptable?

done.
