vxl fails to build if ffmpeg is installed

[jwhowse4@…]

On an intel mac running Leopard 10.5.6 and Xcode 3.1.2 vxl fails to build with the following error. It looks to me as if this may be related to the fact that I can not update ffmpeg. Any suggestions?

When I deactivate ffmpeg 0.4.9-pre1_12, vxl builds and installs correctly.

$ port installed ffmpeg
The following ports are currently installed:
  ffmpeg @0.5_2 (active)

[devans@…]

I'm just guessing but is it possible that vxl is building using its own internal copy of ffmpeg (many ports do) which is not compatible with our installed version and it is looking for include files/libraries in the MacPorts system path before it looks for the ones that are local to vxl?

This would explain why it builds when port ffmpeg is not present.

[toby@…]

I'm not disputing that it's broken... I just can't be bothered to install ffmpeg and its billion deps.

This should be fixed now; see #24654.
