What could it be? I've also tried latest gcc (4.8) snapshot but it didn't help.

p.s.

extra/boost 1.49.0-1 [installed]
core/gcc 4.6.3-1 (base-devel) [installed]
aurbuild/luabind 0.9.1-1 [installed]

As luabind is present as a google google project I was able to browse the code and find which lines are causing the error. They all look like:

#elif BOOST_PP_ITERATION_FLAGS() == 1

It seems others have run into this problem and I found this thread that I hope will help you.
