I've been trying to build audio/arts (dependency of multimedia/mplayer)
on MacOS X 10.2.8 and have run into what appears to be a tools problem.

First, see pkg/30127 and pkg/30129 to see what I've done to get it to
build at all.

Eventually, it fails as follows:

[...]

then mv -f ".deps/tradercheck.Tpo" ".deps/tradercheck.Po"; else rm -f ".deps/tradercheck.Tpo"; exit 1; fi

Has anyone encountered anything like this before, on any package?

I see a reference to this on:

    http://lists.debian.org/debian-gcc/2003/11/msg00191.html

but have only started investigating this problem.

Thanks for any input you can provide.
