Assigning to maintainers.

Looks like another iconv vs. libiconv symbol error, see #13055.

[mcalhoun@…]

Attached is a proposed solution.

With any luck, it would also fix #16526, #16120, #15585.
It would partially address #16859.

There are several lines in the configure.args section of the qt4-x11 Portfile similar to:

    -I${prefix}/include/gstreamer-0.10                         \

If qt is updated to work with gstreamer 1.x (new port gstreamer1) in the future, would looking for 0.10.x headers explicitly like this lead to opportunistic linking?
Are all of these -I flags still needed?
