Rails - May 2006 - subversion password using capistrano on textdrive

Hi,

I am trying to set up capistrano for use on textdrive, and followed
the instructions posted at this very helpful site:

http://blog.tuples.us/pages/rails-guide


My problem is that when I try to execute rake remote:exec
ACTION=cold_deploy  the  execution getss stuck when it tries to access
my subversion repository.

 ** [out :: myurl.com] Authentication realm: <http://myurl.com:80>
myurl.com
 ** [out :: myurl.com] Password for ''bnevile'':
 ** [out :: myurl.com] subversion is asking for a password
 ** [out :: myurl.com] Authentication realm: <http://myurl.com:80>
myurl.com
 ** [out :: myurl.com] Username:


Anybody have any idea how I can avoid this?  Thanks in advance.
Ben
