hugin build failure

[Roger Mason]

Hello,

I have this failure on 10.6.8 (Snow Leopard):

sudo port install hugin-app

This port depends on enblend, which fails thus:

:info:build ../include/vigra_ext/cachedfileimage.hxx:566: error:
‘vigra_ext::cfi_detail::NotifyingDirectionSelector<vigra::UnstridedArrayTag,
T, Notify>::NotifyingDirectionSelector(const
vigra_ext::cfi_detail::NotifyingDirectionSelector<vigra::UnstridedArrayTag,
T, Notify>&) [with T = int, Notify =
vigra_ext::CachedFileImageIteratorBase<vigra_ext::CachedFileImageIterator<int>,
vigra_ext::CachedFileImage<int>, int, int&, int*,
vigra::UnstridedArrayTag>]’ is protected

This is the same error as ticket #44049.

Is anyone aware of a fix?

Thank you.
Roger
