 Yes, that's exactly the situation this test is supposed to detect.\\
 Why is this a problem? Well, sometimes mirrors MacPorts tries to use cease
 to exist. Normally, DNS resolution would fail and MacPorts would just
 gracefully try the next mirror. However, in this case, DNS resolution
 actually does not fail and MacPorts continues to download the file from
 this server. Since MacPorts tries to find the fastest server out of a
 given set of mirrors and these "services" are often run by providers which
 are rather close to you, MacPorts often ends up trying to use these
 "mirrors", downloading an incorrect file and aborting installation. This
 warning is to remind you that this might happen; you should keep it in
 mind if you see a checksum error.

 > it seems that I have to live with the MacPorts warning... :-(

 Most ISPs offering this "service" have a way to turn it off in their
 control panel settings. You might want to check that (or even call them
 and tell them to stop trying to be "helpful"). ISPs can also not force you
 to use their DNS servers – there is a series of alternative DNS servers
 available that you could configure your setup to use instead to work
 around this problem, if you want to.
