 Replying to [comment:21 Ionic]:
 > The selfupdate failed? How did that happen? I can't see CPPFLAGS being
 set in the environment, which is weird. Normally it should now include
 something. Are you sure that you synced up successfully?

 The failure happens at the configure stage (missing script; the target
 folder is empty indeed), before setting the environment variables. The
 tail of debug output is:

 configure: === configuring in vendor/tcl/unix
 (/opt/local/var/macports/sources/rsync.macports.org/release/base/vendor/tcl/unix)
 configure: error: no configure script found in vendor/tcl/unix
 Command failed: cd

 --enable-readline && make SELFUPDATING=1 && make install SELFUPDATING=1
 Exit code: 1

 Error: /opt/local/bin/port: port selfupdate failed: Error installing new

 About syncing with the latest port modification, I was relying on the
 output from livecheck debug, saying:

 DEBUG: Executing org.macports.livecheck (libssh)
 DEBUG: Portfile modification date is Sun Feb 12 00:09:23 CET 2017
