I noted the error on my Mac Book Pro. It is due to a lack of iconv_* functions in MacPorts' libiconv.

I am wondering if I should link to system's libiconv or rewrite iconv_* to libiconv_*.

Somehow, I was able to build g95 from the scratch (before installing other ports).

the patch enables me to build g95 successfully, thanks
