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
