Hi,
 This is a repost and I hope this time it gets someone attention. I have
spend some time trying to make the leda wrapper work with
the new version of leda. I had some success with it. However finally i got
stuck with this error that I couldn't make
any sense of

boost_1_36_0/boost/concept_

It is instantiated from eventually from
boost/concept_check.hpp: In destructor
'boost::SignedInteger<T>::~SignedInteger() [with T = leda::edge_struct*
const*]':
/home/san/ArtOfLearning/boost_1_36_0/boost/concept/detail/general.hpp:29:
instantiated from 'static void boost::concept::requirement<Model>::failed()
[with Model = boost::SignedInteger<leda::edge_struct* const*>]'

It doesn't seems like a big problem. I am sure the original author of leda
wrapper or anybody well versed with the internals can point me
in the right direction.

Thanks
sandeep
