I took it as thorough documentation of problems.  Thanks!

Some of your dependencies are older that what we've been using.
You can find a list here:

http://www.mcs.anl.gov/fl/research/accessgrid/wiki/moin.cgi/AccessGrid3Dependencies

Sorry for the confusion.  A couple notes:

- ZSI:  The release candidate will fix the wsdl2py/wsdl2py.py problem you 
mentioned.
- openssl:  I'm not sure how far back we can go, but I know there were security 
related fixes
   in the latest releases of both 0.9.7 and 0.9.8
- Twisted:  We only use twisted.internet, which you can get as a separate (and 
smaller) bundle
- Bajjer: 0.2.4 fixes a bug which caused the VenueClient to crash on Linux
- M2Crypto must be 0.15 (this will fix the problem with 
ssl_ctx_load_verify_locations)

I wouldn't hesitate to file bugs for issues you find.  It creates a record of a 
problem found
and the solution (even if the solution is "this is not a problem because xyz").
