I currently have sage-4.2 installed on my lenovo netbook.  In the past,
I have been able to successfully install sage binaries, but the latest
version 4.2.1 fails with the message 

                "ImportError: No module named _md5".
 
Checking web for similar errors suggests that this may simply be a issue
of the python module having been renamed from md5 to _md5.  

Information on the specific download, error message, and my machine data
follow:

DOWNLOAD:  sage-4.2.1-ubuntu9.10-AtomN270-i686-Linux

ERROR occurs during the initial load:
