ProFTPD fails to start

hi,

I just installed ProFTPD using 'apt-get install proftpd'.
The installation was successful but it said: ProFTPd warning: cannot
start neither in standalone nor in inetd/xinetd mode. Check your
configuration.
My /etc/proftpd.conf has:

ServerName "rhftp"
ServerType inetd
DeferWelcome off

ShowSymlinks on
MultilineRFC2228 on
DefaultServer on
ShowSymlinks on
AllowOverwrite on

TimeoutNoTransfer 600

DisplayLogin welcome.msg
DisplayFirstChdir .message

# Umask 022 is a good standard umask to prevent new files and dirs

# To prevent DoS attacks, set the maximum number of child processes
# to 30. If you need to allow more than 30 concurrent connections
# at once, simply increase this value. Note that this ONLY works

# that allows you to limit maximum number of processes per service

Can someone tell me what could be/is wrong?
Also i seem to have a 'proftpd' dir. in /etc (/etc/proftpd) inside
there is: modules.conf and proftpd.conf is this normal?
