New description:

 After upgrading from macOS 10.11 to 10.12 and reinstalling MacPorts with
 all the ports, I run into the following problem:

 When trying a
 {{{
 $ sudo mc
 Password:
 }}}
 on macOS 10.12.0 (Sierra), mc throws a
 {{{
 common.c: unimplemented subshell type 1
 read (subshell_pty...): No such file or directory (2)
 }}}

 Searching for this error, I've stumbled over similar problems/bugs
 relating mc on FreeBSD:
 - mc: [https://www.midnight-commander.org/ticket/3658 Ticket #3658 (new
 defect) - Subshell not working with Bourne shell /bin/sh (not bash)]
 - FreeBSD: [https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=208391 Bug
 208391 - misc/mc SUBSHELL not working with /bin/sh]

 I've never had this problem before on macOS 10.11.x and older, and I
 guess, something might have changed on 10.12 relating /bin/sh resp. the
 shell environment.
 Please fix here on MacPorts with a patch or upstream, so that mc is usable
 again with subshell on macOS 10.12.x (Sierra).
