Subdomain module problem

Step 1 now it works, problem due to dns propagation (maybe).
But step 2 fails with 404 error, attached my lighty rewrite: my drupaldir is under home/admin
$HTTP["host"] =~ "([^.]+)\.([^.]+)$" {
evhost.path-pattern = "/home/admin/%2.%1/"
}

# Apply the following drupal rewrite rules to subdomain URLs
# moving subdomain to the 1st argument in the path
# e.g. bob.example.com news.mysite.net
$HTTP["host"] =~ "^([^.]+)\.([^.]+)\.([^.]+)$" {
url.rewrite-final = (
# More than one argument
"^/([^.?]*)\?(.*)$" => "/index.php?q=_%1/$1&$2",
# No arguments
"^/([^.?]*)$" => "/index.php?q=_%1/$1",
)
}

any help?
