I didn't tell since I didn't use it!

I only added the flag today, when clang needed to locate the third-party
X11 and fontconfig dependencies under /usr/local. But then, it is clear
why my earlier build succeeded: it didn't build xdvi at all (thanks to
--without-x).

Okay, that sounds credible (but nasty). Your log:
checking for iconv.h... yes
checking for library containing iconv... none required

My log:
checking for iconv.h... yes
checking for library containing iconv... no

It just reads strange that libxdvi.a incorporates util.o, which is
compiled with -I/usr/local/include (l. 37252), but linking of xdvi-bin
with -L/usr/local/lib then fails.

pkg info -r converters/libiconv
libiconv-1.14_11:
        rsync-3.1.2_7
        glib-2.50.2_6,1 (which is needed by editors/vim)
