Just looked at the logs. I'm 100% sure that the reason is as follows:
bsd's iconv.h gets included instead of libiconv.h since linker says that
undefined reference to `iconv_open(char const *, char const *)'
(I.e. not "undefined reference to iconv_open" - this means that declarations
not wrapped inside of 'extern "C"' are seen - and as you've said libiconv's
iconv.h wraps them around 'extern "C"' and BSD's one doesn't, it's clear
what header gets included).
Fix this by putting -I/usr/local/include in CFLAGS so that libiconv's iconv.h
is seen instead of BSD's one and recompiling all files that include <iconv.h>.
