Alternative Idea:
Use Sun Virtualbox on Mac:
Download:
 http://www.virtualbox.org/wiki/Downloads
*Choose Version
*OSX, Windows, Linux, other.

Read this First:
http://people.sugarlabs.org/Tgillard/soas-2-blueberry_ovf_README_FIRST.txt
3 files to download:
  http://people.sugarlabs.org/Tgillard/soas-2-blueberry.mf
  http://people.sugarlabs.org/Tgillard/soas-2-blueberry.ovf
  http://people.sugarlabs.org/Tgillard/soas-2-blueberry.vmdk

*Start  Sun Virtualbox ( I used: Version 3.1.4 r57640 for export)
Top Left Corner of window:<file><Import Appliance>

<Choose> (to find 3 downloaded files you just downloaded )

select: soas-2-blueberry.ovf
<Appliance Import Settings> Window appears:
*Correct line: "Guest OS Type" to OS:linux  Version:fedora (click on Other/unknown it is a  dropdown box)
*Agree to GPL license
*<Import>

*start sugar

Notes:

1-) the 3 files can be configured to be located on a USB stick.

2-)http://wiki.sugarlabs.org/go/VirtualBox#Virtualbox_3.2.1_on_16GB_Toshiba_USB_Running_Ubuntu_9.10_Karmic

This is a nice portable solution for a full Gnome Desktop and Sun 
Virtualbox 3.2.1 (works with Hp Pavillion "Vista"Notebook) I use it to 
create .vdi Hard Disk images for soas-v2-Blueberry

   1. install Ubuntu 9.10 [1] <http://www.ubuntu.com/GetUbuntu/download>
      from CD to 16GB Toshiba USB (It will run on 8GB USB but very
      little room left for images)
   2. setup wireless networking
   3. Download VirtualBox: [2] <http://www.virtualbox.org/wiki/Downloads>
   4. Install Virtualbox

> The best near-term option might be if someone created a live-usb stick on Linux or Windows, and zipped up the files it created. Extracting those on another stick might work (I'm not entirely sure how the live usb booting works). Alternatively, a disk image of the whole live usb stick could be made, distributed, and written on other sticks using image-writer-mac. This would be less flexible because it only has a fixed size (e.g., snapshotting a 1 GB stick and putting the image on an 8 GB stick would leave 7 GB unusable) but I can't see why it shouldn't work.

I was able to boot it with the extra step of holding down the "c" key while booting with the boot helper disk and then "Tab" and editing the text that appears on the screen as suggested by George below).

>>
>> The MacBook, requires a boot helper disk that looks for a usb stick named FEDORA.  I suspect they wrote it that way so it can also be used with Strawberry and with other future versions of SoaS. However, this stick is named  "soas-2-blueberry", not FEDORA.
>>
>> Well  I tried to rename the usb stick "FEDORA" when it was finished so I could use it on the MacBook, but, try as I may, I cannot change the name.  I even tried it on Ed's computer too (a G4 Powerbook) with no luck.  I can change the name of any other file or other usb stick, but not this one.  It is apparently "soas-2-blueberry", forever.
>>
>> I even tried another tack.  I changed the name of the "soas-2-blueberry.iso" file to "FEDORA.iso" before going to terminal to run the image-writer-mac program again and make another stick.  It still wrote the name as "soas-2-blueberry". So now, I have made 2 SoaS usb drives I can probably use on PCs, but not on Macs.
