Comment (by mf2k):

 So I think all of the tickets we have been waiting on have been resolved.
 I am going to attach my latest version of the Portfile as a starting point
 for this. It fails at the configure phase as follows:

 {{{
 :info:configure checking for library containing iconv_open... no
 :info:configure configure: error: in
 `/opt/local/var/macports/build/_opt_local_var_macports_sources_github
 .com_macports_macports-ports_x11_i3/i3/work/i3-4.15/x86_64-apple-
 darwin16.7.0':
 :info:configure configure: error: cannot find the required iconv_open()
 function despite trying to link with -liconv
 }}}
