capistrano issue

Hi,

capistrano is driving me crazy !!!

i use the following recipe :

set :user, "myUserName"
set :password, "myPwd"

set :application, "hellodeploy"
set :repository, "http://mysvnrep.mydomain.net/hellodeploy"

role :web, "deploytest.mydomain.net"
role :app, "deploytest.mydomain.net"
role :db, "deploytest.mydomain.net", :primary => true

set :deploy_to, "/home/#{user}/deploytest.mydomain.net"
set :use_sudo, false
set :checkout, "export"

the setup action performed correctly
so i confindently launched the deploy (rake deploy)

i got a permission denied on the call of reaper.
it appears that none of the files you could expect to be executable are effectively correctly chmoded, they all are rw-r--r-- : reaper and co, dispatch.fcgi and co either !

By the way, when i wrote the db role, i had to use the same server than web and app. But actually it is a different one : test-svn-db.mydomain.net. Using this one caused the setup action to fail. WHY ?

Could anyone explain a clear, clean way of putting capistrano on the rails ? (Easy, i admit but it's friday, may i be forgiven ;-) ) That is : servers names, and so on.

TIA
