Hi Moritz,
I can report the issue here, I did :-)

Eeh, don’t you see:

It seems to be there...
MacBook-Pro:ffmpeg-build-script bouke$ locate fontconfig.pc

However, I don’t really need libfontconfig it seems. (I don’t need font substitudion, this is for a very specific project for just a couple om machines.
Leaving —enable-libfontconfig out let me build on the machine that failed before.

I have no clue… But the dowloads from evermeet.cx <http://evermeet.cx/> / gyan.dev always work, so it ’should’ be possible.

On ‘clean’ machines I still get:
dyld: Library not loaded: /usr/local/opt/freetype/lib/libfreetype.6.dylib

But at least I have a bit hope my client is able to run the script.
