Anyways, simply removing the attempted execution of the binary mplayer's configure script is using to test pthreads fixes the issue. I found this solution from some FreeBSDer's post to the mplayer-dev list or something -- see inline patch. The problem with my patch is that I'm not really sure whether the functions that deal with pthread may be broken, though the rest of mplayer is working correctly?

please try pre3
seems to be fixed with pre3
