> This seems to be related to having a macports install of libiconv. The compile step for sysutils.c puts the macport include header before /usr/local/include but the link step for libR doesn't - in fact it doesn't include a -L for the macport directory at all. So there is an an inconsistency in the expected symbols. (Why the macport version defines libiconv_open instead of iconv_open I have no idea).

FWIW, the workaround we now use is to specify -DLIBICONV_PLUG, because then all libiconv variations behave the same.
