Comment (by mascguy):

 The addition of dep `libfmt` was done for cleanup purposes, as the port
 was already taking advantage of it. But previously it was pulled in
 indirectly, via an upstream dep. (So materially there's no difference than
 previously, except that now we're formally calling out the dep.)

 As for the issue, this is likely due to breaking changes in `libfmt`,
 which impacted older versions of `mkvtoolnix`. So we may need to patch the
 code. (The breakages are tracked by issue:65619.)
