Does not work with SDK 1.8.3

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install SDK 1.8.3 
http://googleappengine.googlecode.com/files/google_appengine_1.8.3.zip
2. Follow installation instructions for a sample app
3. Start dev_appserver
4. Go to http://localhost:8080

What is the expected output? What do you see instead?
App will run

What version of the product are you using? On what operating system?
There are import errors from the use of simplejson 

Please provide any additional information below.
If those imports are fixed (e.g. by replacing simplejson by json) there are 
further import errors caused by importing dev_appserver directly.

Also, the overview.py webapp is set up for CGI use, which is incompatible with 
having threadsafe=true in app.yaml

I'm on 1.9.8
After fixing the simplesjon import as above it seems to not work in dev 
appserver sandbox:

apptrace/guppy/sets/__init__.py", line 3, in <module>
    from setsc import BitSet    # base bitset type
  File "/usr/local/google_appengine/google/appengine/tools/devappserver2/python/sandbox.py", line 852, in load_module
    raise ImportError('No module named %s' % fullname)
ImportError: No module named guppy.sets.setsc

this seems because Guppy is not a pure Python module and falls foul of the 
sandbox
