No, for once you're mistaken - fontconfig is only used in Linux or similar (X11) environments, not on OS X or Windows.

(Hmm, it might be used on Windows if people are using personal builds along with libraries from KDE/Win or whatever.... I'm not entirely sure. It's not used by the builds I distribute, though.)

Yes, that's correct.

I don't think so; I'd be very surprised if that were the case. I think this indicates that you've installed something - such as MPlayer - that was ported from an X11 environment, and not adapted to use native Mac font management. Perhaps even something that runs within the X11 environment on OS X.

Truly "native" Mac programs will not be affected by these files, however.
