Install Oracle 10g or 9i failed with FreeBSD 5.4-RELEASE

[hshh]

Hi,
I just installed FreeBSD 5.4-RELEASE.
Installed xorg-6.8.2 and xfce4-4.2.1.

I was follow http://ezine.daemonnews.org/200402/oracle.html ,and want
to install Oracle into my box, but failed.

I tried use Linux_base-7/linux_devtools-7,
Linux_base-8/linux_devtools-8, none was work.

The Oracle Installation was freezen, and the java process used 100% cpu.

What can I do?
