That "proof" is completely (well, almost) irrelevant for end users.  It 
matters for port developers, but once a port is "published", its distfiles 
are copied to the MacPorts mirrors, where they can be fetched by the 
system curl on any OS.

The "almost" is because the primary distfile source is still included as a 
candidate for fetching, and in some cases may be chosen ahead of the 
mirrors.  In the non-working curl case, this at the very least adds delay, 
but there was a case a couple of years ago where MacPorts decided to 
prefer to the mirrors (at my location), and the fetch (on 10.9) 
would hang in a way that wasn't subject to a timeout, so it never gave up 
and never moved on to the mirrors.  The response when I reported this was 
"gee, it's supposed to have timeouts".  I don't know exactly what got 
fixed, but I haven't seen this lately.

Livecheck is completely different, since there's no mirroring of the 
content that livecheck is looking at.
