Summary: No clang or gcc invocation incantation seems to produce
avfoundation indev support.
Need someone smarter than me to suggest how I can debug this, to
produce a Portfile fix for MacPorts.
Thanks.

Yesterday I fired up ffmpeg to capture a MacBook Pro iSight Webcam stream.
Sounds easy... Ugh... Not so...
Here's the problem... (All examples using latest git pull.)
David-Favor-iMac# git describe
n2.0-10562-g229a1e8
First... let's see if configure knows enough to ferret out avfoundation...
David-Favor-iMac# ./configure --list-indevs
alsa iec61883 pulse
avfoundation jack qtkit
bktr lavfi sndio
dshow libcdio v4l2
dv1394 libdc1394 vfwcap
fbdev openal x11grab
gdigrab oss
Great... configure discovers both avfoundation + old deprecated qtkit...
So far so good...
When configure runs... still looks good...
Enabled indevs:
avfoundation lavfi qtkit
And compilation passes...
...
CC libavdevice/avfoundation.o
CC libavdevice/lavfi.o
CC libavdevice/qtkit.o
...
Adding or leaving out specific indev enabling has no effect on final
executable...
--enable-indev=qtkit --enable-indev=avfoundation
The only effect is if clang is used, qtkit indev available + if gcc-4.8.2 used,
then qtkit indev is missing.
Neither clang or gcc-4.8.2 produces avfoundation indev.
Compile system is latest OSX + XCode + MacPorts.
