configure: error: *** No iconv() implementation found in C library or libiconv
===>  Script “configure” failed unexpectedly.
Please run the gnomelogalyzer, available from
“http://www.freebsd.org/gnome/gnomelogalyzer.sh”, which will diagnose the
problem and suggest a solution. If – and only if – the gnomelogalyzer cannot
solve the problem, report the build failure to the FreeBSD GNOME team at
gnome@FreeBSD.org, and attach (a)
“/usr/ports/devel/glib20/work/glib-2.36.3/config.log”, (b) the output of the
failed make command, and (c) the gnomelogalyzer output. Also, it might be a
good idea to provide an overview of all packages installed on your system
(i.e. an `ls /var/db/pkg`). Put your attachment up on any website,
copy-and-paste into http://freebsd-gnome.pastebin.com, or use send-pr(1) with
the attachment. Try to avoid sending any attachments to the mailing list
(gnome@FreeBSD.org), because attachments sent to FreeBSD mailing lists are
usually discarded by the mailing list software.

こんなのが出てきてglibのコンパイルができない（FreeBSDのports）
pkg_add -r glib20して回避ｗ
美しくないｗｗｗ
