The build phase for print/xdvik fails at this point:

Stop.

The problem seems to be that the build picks up /usr/local/include/iconv.h
instead of /usr/include/iconv.h.  The former include file has #define
statements that rename iconv_open to libiconv_open, etc.  This would
probably work if the port also listed libiconv as a dependency and linked
against /usr/local/lib/libiconv*, but neither of these is true.
The configure script doesn't add -L/usr/local/lib to the command line
when it is checked to see if it should link with -liconv.

This probably used to work before iconv was added to the libc because
configure would not have found iconv support.

How-To-Repeat: 
Attempt to build the port on a version of FreeBSD that includes iconv
in libc.
