Problem with sftp and paramiko

[micky]

Hello,

when i try a connect to a bazzar machine via sftp with the command line,

bzr branch ftp://<username>@<ip><path>

i got the error,

bzr: ERROR: Unsupported protocol for url "sftp://<username>@<ip><path>":
Unable to import paramiko (required for sftp support): cannot import
name util


I have compiled bzr-1.1 with sftp support and paramiko-1.7.2. Here still
the entry in the log message.
