Comment (by ryandesign):

 In src/macports1.0/macports.tcl we have:

 {{{
 # Determine dependency types required for target
 proc macports::_deptypes_for_target {target workername} {
     switch -- $target {
 }}}
 {{{
         install     -
         activate    -
         {}          {
             if {[global_option_isset ports_binary_only] ||
                 [$workername eval {registry_exists $subport $version
 $revision $portvariants}]
                 || (![global_option_isset ports_source_only] &&
 [$workername eval {_archive_available}])} {
                 return "depends_lib depends_run"
             } else {
                 return "depends_fetch depends_extract depends_patch
 depends_build depends_lib depends_run"
             }
         }
 }}}

 If an archive hasn't already been downloaded, `[$workername eval
 {_archive_available}]` uses curl to check if an archive is available on
 the server. I think the problem is that the Travis network connection was
 unavailable briefly—while we were running `port archivefetch` (all
 attempts to download an archive failed) and when we started running `port
 fetch` (the first distfile download attempt failed; the second one
 succeeded). By the time we ran `port install` the network was back up so
 it could see that an archive was available so it only added lib and run
 dependencies, but by that point we had already marked the archivefetch
 phase as complete so we tried a source build which failed because the
 build dependencies weren't there.
