There is a slightly different way, that was explained to me by William
off list. There is no need to download the extra fortran package
manually, so, perhaps it is very slightly easier.

1. Get the sources, untar them.
2. $ export SAGE64=yes
    $ cd sage-4.1/
    $ make
3. Wait until it fails.
4. $ ./sage -i fortran-OSX64-20090120
    First it was a bit surprising to me, but "./sage -i" works even
though the build process failed.
5. $ make
    This time it should work
6. Comment out the line that imports cliquer in SAGE_ROOT/devel/sage/
sage/graphs/all.py

Now ./sage works.

Cheers,
Simon
