It should. It calls:

$ test_cmd $pkg_config --exists --print-errors $pkg_version || return

in test_pkg_config(), which is called from check_pkg_config(), which
is called from require_pkg_config(), which is called from:

$ require_pkg_config libfreetype freetype2 "ft2build.h FT_FREETYPE_H" FT_Init_FreeType

But it also checks the availability of the function FT_Init_FreeType()
in the given headers. Perhaps part of that doesn't work in your
install.

Can you show us the first ~2 and the last ~50 lines of
ffbuild/config.log?

Which version of ffmpeg are you trying to build? Latest git master?
