Is this a duplicate of #19851? Can you verify that this is the latest version of the port? This iconv stuff changed again?

[conradwt (Conrad Taylor)]

Yes, I was attempting to install doxygen version 1.5.9.

Looks like it is detecting libiconv_open (probably in macports' libiconv), but attempting to link against the system iconv, which doesn't contain the deprecated libiconv* symbols
