Subject: net/ftp problem

I'm trying to recurse a directory and chmod the files on a remote ftp site.
What happens in the code works for the root directory then when it hits a
child directory and calls the chmod function recursively it hangs on the
next access of the 'conn' object.  I cannot figure it out.  Here's the code:

-----------------------------------
require 'net/ftp'

def print_info(msg)
    puts Time.now.to_s + " :: #{msg}"
end

def chmod_files(conn, dir)
    conn.chdir(dir)
    pwd = conn.pwd()
    conn.list() { |entry|
        fileName = entry.split()[8]
        print_info("CHMOD #{PERMISSIONS} #{fileName}")
        conn.sendcmd("SITE CHMOD #{PERMISSIONS} #{fileName}")
        if entry =~ /^d/ # It's a directory
            chmod_files(conn, fileName)
            conn.chdir("..")
        end
    }
end

## Main
HOST        = ARGV[0] || "localhost"
PERMISSIONS = ARGV[1] || "0775"
STARTDIR    = ARGV[2] || "."

print_info("Host = #{HOST}")
print_info("Permissions = #{PERMISSIONS}")
print_info("Start Dir   = #{STARTDIR}")

Net::FTP.open(HOST) { |conn|
    conn.login("blahID", "blahPass")
    chmod_files(conn, STARTDIR)
}
--------------------

Any help would be appreciated.  I've wasted a lot of time on this....Please
tell me the standard libraries are getting better?
