A file not being available on a packages server is not a bug. See #68869. Also, packages servers are used for all ports; they are not specified in individual ports. In the case of stardict, the packages are not on the server because we believe we are not legally allowed to distribute them:
$ macports-infrastructure/jobs/port_binary_distributable.tcl -v stardict
"stardict" is not distributable because its license "gpl" conflicts with license "EPL-1" of dependency "graphviz"
A file not being available on a distfiles server can be a problem. In this case, I don't know why you were not able to fetch from SourceForge; I am able to. If you want help diagnosing why you couldn't fetch, attach your main.log. Even though you couldn't fetch from SourceForge, it wasn't a problem since we mirror distfiles, so you were able to fetch it from the mirrors, and the build succeeded. So I don't see any bug here.
