Use capistrano to symlink you shared files, don't build a wheel inside of the car while you're driving the car

gistfile1.rb

# WHY? Capistrano has already made this super easy for us to do, AND, 
# capistrano is already doing this for us for pids, log, and system files.
desc "Create socket file symlink for nginx"
task :symlink_sockets, :except => {:no_release => true} do
  run "mkdir -p #{shared_path}/sockets"
  run "ln -s #{shared_path}/sockets #{release_path}/tmp/sockets"
end

# utilize that capistrano has already done this!
#
# If you put your shared file or folder here:
#   /path/to/app/shared/sockets
# Then it will be symlinked here:
#   /path/to/app/releases/20120517191233/tmp/sockets
