I've pushed a modified version of README.MacOS

        http://hg.savannah.gnu.org/hgweb/octave/rev/2ba904181687

The section on describing "Manual Package Management" is still empty. I was 
pleased to see the several emails exchanged on this subject. Unfortunately, I 
have been unable to keep up.

I encourage those who are building without Fink and MacPorts to propose 
instructions that can be inserted into the current version. Changesets are 
preferred, but I am happy to handle a diff as well.

We may wish to include 32bit and 64bit sections.

Thanks
Ben
