Installing bzr.dev over 0.18.0 failed

[Rene Leonhardt]

bzr 0.18.0 was installed, tried to install the current bzr.dev over it 
in order to try to get the bzr-svn plugin together with the new 
unofficial svn Python bindings working on Windows for the first time 
(but failed once again):

In case someone wants to know, after removing the old 
C:\Python\lib\site-packages\bzrlib and reinstalling bzr.dev, "bzr 
selftest svn" now immediately stops with "bzr: ERROR: Unable to import 
paramiko (required for sftp support): cannot import name util".
