"easy_install -U twisted" isn't something we ever test or claimed to 
support.  I don't recall anyone ever asking for support for it either. 
We do test "easy_install <local twisted tarball filename>" and that 
works, at least on Python 2.5, on Twisted 11.1.  We don't test it on any 
other Python version.

Apart from the same comments about -U above, I don't recall this error 
on PyPy ever being reported.  The install errors we fixed had to do with 
extension compilation, not a failure to import the name 'copyright'.

Please file tickets for issues you encounter or features you'd like 
supported.  For these, the testing path likely involves setting up a new 
BuildSlave in the appropriate environment, so if you can donate hardware 
to run these slaves, that would help out a lot.  Otherwise we're not 
likely to be able to test the configurations, so they won't be 
supported.

Thanks,
Jean-Paul
