I don't see what setuptools has to do with this.  
"easy_install subvertpy" works fine here.

This is unrelated to bzr-svn, but to pycurl which is used by bzr (and
does not support self-signed certificates).

New versions of bzr will prompt for a username and password (bzr >=
1.15). You can also specify username/password in the branch URL.

This is a known bug in 0.5.3, it should be fixed in 0.5.4.
Alternatively, you should be able to specify --layout trunk1.
