I have downloaded and built from the OpenSourceLabs site to my Ubuntu Linux workstation successfully in the past 2 days. However, early on I have seen a simiilar issue to the one you describe (this was about a year ago) where the download hung. I talked with Wind River and they had no explanation - and when I tried it again the next day it worked fine.
So...I would try it again today. If it doesn't work, capture the error in a log and post it here (just the last relevent lines if it hangs). I will forward to Wind River and get a resolution.
Not that it should matter, but what OS are you using on the host where you are attempting the clone?
