oops, the README was wrong! '-A' is missing. Now fixed.
An known working example from nsls2 can be seen in
debian/channelarchiver-a2aproxy.default in the source tree.

twistd is picky about ordering of arguments as these are parsed by
different code. Arguments before the application name ('a2aproxy' in
this case) are for twisted itself (run 'twistd -h'). The remaining
arguments are for the application. (run 'twistd a2aproxy -h')

Switch to some other directory and retry.
By default python searches the current directory before /usr/local. I
would guess that, after installation, your shell is still in the source
directory, so 'import carchive' finds the copy in the source tree which
doesn't contain the generated files.
> python -c 'import carchive; print carchive.__file__'
Will show the path of the module which was imported.
