Comment (by ryandesign):

 As was discussed in #66931, the problem appears to be unique to a few
 users' systems. The build system is supposed to be adding `-liconv` on its
 own. Manually adding that flag is a poor workaround; we would prefer to
 figure out why the build system is not adding that flag when it should and
 fix it to do so and submit that fix to the developers so that everyone,
 not just MacPorts users, can benefit.
