Could you try the following workaround? Just add the code to 
boost/dynamic_bitset/dynamic_bitset.hpp, just after the definition of the 
class dynamic_bitset. Note that you probably may have to play around with 
the syntax a bit, this is from the top of my head and not tested.

#if BOOST_WORKAROUND( __IBMCPP__, <=600 )

template<typename Block, typename Allocator>
dynamic_bitset<Block, Allocator>::block_width_type const
dynamic_bitset<Block, Allocator>::bits_per_block;

template<typename Block, typename Allocator>
dynamic_bitset<Block, Allocator>::block_width_type const
dynamic_bitset<Block, Allocator>::ulong_width;

#endif
