Comment (by glebm):

 I think the problem might be the following line in the Portfile:

 {{{
 compiler.cxx_standard 2011
 }}}

 When built in this configuration, libfmt builds its own version of
 string_view, optional, etc.
 This is a fallback configuration that is not compatible with C++17
 programs, so it probably shouldn't be the default one.

 > I maintain older versions of libfmt, so I'll take a look

 I thought libfmt11 was the latest version available in macports, did I
 overlook something?
