It is related to MacPorts' libiconv.

MacPorts' libiconv does not have symbols iconv_*.

There are libiconv_* instead.

System's libiconv have both.

A quick google search tells me that it is a cause of

build failure of a few other packages.

Could you tell me if

1) iconv_* are deprecated and I should rewrite them to libiconv_*,

2) system's libiconv should be used, or

3) I should wait an update of libiconv package?
