problem with fresh MacPorts install on 10.13

[Noam Bernstein]

Hi - I’ve been happily using MacPorts for years, and just had a weird problem.  I’m trying to install it on an OS X 10.13 machine, fresh install, MacPorts version says 2.5.4 (and I did selfupdate and upgrade outdated).  When I do
port install gcc8
(or any other gcc version I’ve tried so far) it says
Error: dependency ‘libiconv’ not found.
indeed, when I do
port search libiconv
all I get are php??-libiconv options, not libiconv itself.  When I check the web site for available ports, it lists libiconv 1.16, but my installation doesn’t seem to know about it.

Does anyone have any idea what’s going on?
