Summary: Import random fails 

Initial Comment:

import random fails.

There is no /dev/urandom on this machine, so
os.urandom raises:

NotImplementedError: /dev/urandom (or equivalent) not 
found

The code in random.py seems to expect that 
os.urandom exists that urandom will work.

Possible patch:

Change random.py so that that urandom usage
is setup like this:

try:
    from os import urandom as _urandom
    from binascii import hexlify as _hexlify
except ImportError:
    _urandom = None
else:
    try:
        _urandom(1)
    except NotImplementedError:
        _urandom = None


After this, import random works. test_random
still fails for the HardwareRandom tests, of course.

Glad to hear the bugs patch worked for you.

Afterwards, I made further updates.  Would appreciate it if
you click on this bug report and get the two new files from
SF and make sure they work on your machine.

Sorry that it has taken me so long to reply. We did not have 
a patch that understood unified diffs. I have applied the 
random patch from the bugs page and make test is not 
reporting any problems any more. Thanks for the prompt fix.
