[Optional] Trunk build broken as of 20100721

[ramon.casellas@…]

May be related to some optional changes or lack of include between graph/Property Tree/XML/GraphML:

In file included from ./boost/property_tree/stream_translator.hpp:17,

Thanks in advance

Even if it a missing include in BGL that triggered the problem, Boost.Optional is supposed to have all of the necessary includes for its own functions to work.

The fix seems trivial and related to optional changes:
