At the gettext configure check for -lintl, it fails on openbsd with:
/usr/local/lib/libintl.so.2.0: undefined reference to libiconv_open' /usr/local/lib/libintl.so.2.0: undefined reference to
libiconv_close'
/usr/local/lib/libintl.so.2.0: undefined reference to `libiconv'
Adding -liconv makes it pass this configure test.
