[dune-fem] [Dune] Dune on Mac OS X - Segmentation Fault

[Alasdair McLeay]

I've reverted to dune 2.1.0 and dune-fem 1.2.1 and am now able to compile dune-fem-howto (it didn't compile with dune 2.2).

The examples I've tried in dune-fem-howto so far run without memory exceptions, so I'm guessing the issue could be with dune-fem 1.3.

(unfortunately dune-fem-school requires dune-fem v1.3 but hopefully I'll be able to figure out what I need from the dune-fem-howto examples).

I've written an installer script for Mac OS X so please let me know if anyone wants a copy.

Thanks,
Ali
