MacPorts uses libcurl, so what happens if you try downloading the file
with curl? If it gets stuck, you can probably pass it some debug flags
to see what's going on. If not, the definitive tool for debugging the
download problem would be wireshark.

As a workaround, you can add www.kernel.org to host_blacklist in
macports.conf so you can update your ports in the meantime.
