You didn't give the actually failing gcc command-line.
Did you use --enable-static? That makes such issues quite likely, because with that it's necessary to specify even indirect dependencies and it seems they are missing.
I you did not use that, something went very wrong, MPlayer should be linking against the .so files, not the .a files.
