XAMPP install problem

[Tjkhan]

I installed xampp just like apachefriends.org instructed.
But after install, when I input this

/opt/lampp/lampp start

It says "XAMPP is currently only availably as 32 bit application. Please use a 32 bit compatibility library for your system." in terminal.

What am I doing wrong?

I am familiar with XAMPP because I used Windows for a long time.
Can anyone tell me what to do to fix it?

If not in this case, please let me know about lamp with details. I need details because I never used that and NO idea about phpmyadmin.

Thank you.

Additional info: i7, 16GB RAM, Ubuntu 13.04 Raring Ringtail

LAMP installs with one command and a reboot.

Which kind of details do you want?
