Comment (by cal@…):

 Manually downloading might certainly work, yes. You can try that, but it's
 tedious, if it keeps failing with other packages. You could also try a
 different mirror by removing `packages.macports.org` from the file at
 `$(port dir yubico-pam)/../../_resources/port1.0/fetch/archive_sites.tcl`.
 If that helps, we can draft the necessary directives to put into
 macports.conf to make this change permanent (otherwise the next selfupdate
 will revert it).
