It's possible that it always finds the iconv headers from MacPorts
first regardless, then it fails linking with the SDK one due to
mismatched headers and lib.

By experience, there are several "versions" of the iconv symbol names.
This is meant to make it possible to link with an external libiconv or
the one included with the libc on some platforms.
For ex. when defining LIBICONV_PLUG.

If it picked up the wrong headers then it will try to use wrong symbols.
