Fetch of xz distfile fails - connection timeout()

[richard@…]

expected results: latest version of xz, 5.0.5, retrievable from ​http://tukaani.org/xz/

actual results: as per macports log file, fetch fails due to connect() timeout on all mirrors.

thus, any package depending on xz (e.g., gtk2) fails to download.

=================================== pertinent log file contents:

however, when executing curl from the command line, this output:
