[centos-users 1338] /etc/init.d/vboxdrv setupのエラーを回避したいのですが

[ueda.katuhiko ＠ wave.plala.or.jp]

CentOS 5.3にVirtualBox-3.1-3.1.4_57640_rhel5-1を入れたのですが

VirtualBox起動時
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (2.6.18-164.el5) or it failed to
         load. Please recompile the kernel module and install it by

           sudo /etc/init.d/vboxdrv setup
とメッセージが出ます。OS起動時もvboxdrv のモジュールの 読み込みに失敗しています

そこで rootにて以下実行しましたが、失敗します
[root ＠ localhost ueda]#  /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel module                          [  OK  ]
Recompiling VirtualBox kernel module                       [失敗]
  (Look at /var/log/vbox-install.log to find out what went wrong)

ログを見てみると以下のようになります

[root ＠ localhost ueda]# cat /var/log/vbox-install.log

You can use the --kernelsourcedir option to tell DKMS where it's located.

以下の様に、コンパイルに必要なソースはあるつもりなのですが？？

わたしの環境に合っていないのでしょうか??　アドバイスお願い致します
