Update Octave Wiki for Mac OS X Build Instructions

[Todd Rovito]

Hello,
    I would like to help with Octave development so I am getting
familiar with the project and trying to see where my skill set fits
in.  My first task was trying to get Octave to compile which took some
time to figure out but I now have it compiling and running on Mac OS
X.  I documented the build process in a script file here:
   http://dl.dropbox.com/u/3649012/Octave-Build/create-3.2.3.sh

I started with the build script from the Octave-Forge site that is
used to build Octave.app.  The Octave-forge script didn't work on 10.6
so I made some modifications.

The first thing I would like to do is update the wiki Mac OS X
instructions here:
          http://wiki.octave.org/wiki.pl?OctaveForMac

because the instructions don't work for Snow Leopard 10.6 and version
3.2.3 of Octave.   Is it possible for me to get the password to the
wiki so I can make the change?

If anybody has any notes/pointers/documentation they want to send to
me on building Octave for Snow Leopard I would be glad to include on
the Wiki or in the build script.

Thanks.
