Hi,

Just a sneak preview: when using the current boost release 1.45.0 (which
isn't packaged on the major distributions yet) DOLFIN build breaks:

In IntersectionOperatorImplementation there are conflicts with
boost::optional and the
  error: dereferencing pointer \u2018<anonymous>\u2019 does break
strict-aliasing rules
is thrown (boost/optional/optional.hpp 317, 424)

It works using gcc 4.5 though, hence it shouldn't be much of a problem
(unless of course you want to use CUDA: nvcc isn't compatible to gcc 4.5).
