[Dovecot] compiling dovecot on aix gcc 3.3.2

[funkypunky drunky]

I am writing step by step.
1 ./configure --with-ssl --with-ldap
2 make
3 make install
This is my config

protocols = imap imaps pop3 pop3s
listen = *
disable_plaintext_auth = no
log_timestamp = "%b %d %H:%M:%S "
ssl_disable = yes
login_user = dovecot
login_processes_count = 25
login_max_processes_count = 128
login_greeting = Microsoft Exchange POP3 server version 5.5.2653.23 ready
default_mail_env = maildir:%h
mail_log_prefix = "%Us,user=<%u>,lip=%l rip=%r method=%m %c: "
verbose_proctitle = yes

protocol imap {
login_executable = /usr/local/libexec/dovecot/imap-login
imap_max_line_length = 65536
mail_plugin_dir = /usr/local/lib/dovecot/imap
mail_plugins = quota imap_quota
login_greeting_capability = yes
imap_client_workarounds = outlook-idle
}

protocol pop3 {
login_executable = /usr/local/libexec/dovecot/pop3-login
mail_executable = /usr/local/libexec/dovecot/pop3
pop3_uidl_format = %08Xv%08Xu
mail_plugins = quota
mail_plugin_dir = /usr/local/lib/dovecot/pop3
pop3_client_workarounds = outlook-no-nuls
}
auth_executable = /usr/local/libexec/dovecot/dovecot-auth

auth_process_size = 256
auth default {
mechanisms =  plain login
passdb pam {
  }
  passdb ldap {
    args = /usr/local/etc/dovecot-ldap.conf
  }
  userdb passwd {
  }
  userdb ldap {
    args = /usr/local/etc/dovecot-ldap.conf
  }
user = dvctauth
  socket listen {
    client {
path = /var/spool/postfix/private/auth
mode = 0666
 user = postfix

group = postfix
  }
  }
}
dict {
}
plugin {

  quota = maildir
  trash = /etc/dovecot-trash.conf
}
Then i start dovecot. It returns an error.
Edlopen(/usr/local/lib/dovecot/imap/lib10_quota_plugin.so) failed: Could not
load module /usr/local/lib/dovecot/imap/lib10_quota_plugin.so.

As you know /usr/local/lib/dovecot/imap/lib10_quota_plugin.so is a link.
lrwxrwxrwx   1 root     system           24 Mar 22 01:54
lib10_quota_plugin.so@ -> ../lib10_quota_plugin.so
I look to directory /usr/local/lib/dovecot/ but there is no
lib10_quota_plugin.so
