That only happens when compiling a 64 bit version.
You can always compile a 32 bit one (which might be the reason why it
works for some, probably they are on older hardware where Lion runs in
32 bit mode).

That is an AVX instruction. MPlayer does not use AVX currently.
Thus it is generated by the compiler.
So now your binutils is too old for your compiler.
