ffmpeg 2.4.1 "error: instruction requires: Not 64-bit mode"

[peter@…]

I'm getting a failure to build ffmpeg 2.4.1 (specifically, upgrading from ffmpeg@2.3.3_1+gpl2+gpl3+nonfree+x11.) on Mavericks (10.9.5) with xcode 6.0.

The error is during the build of ilpack.c in lavfilter:

port log ffmpeg

Apologies, I think this was caused by using a different /bin/sh and /bin/bash, I tried using the macports /bin/sh and /bin/bash and after a port clean ffmpeg everything rebuilt fine (ffmpeg@2.4.1_0+gpl2+gpl3+nonfree+x11)

ffmpeg @2.4.1_0+gpl2+gpl3+nonfree+x11 also works for me on Mavericks as does ffmpeg-devel @20140925_0+gpl2+gpl3+nonfree+x11.

Thanks for your update.
