Error when trying to install and run phpMyAdmin on Joomla 15 jumpbox

I have a Joomla 1.5 jumpbox.

I followed the instruction at this location:
[url]http://wiki.jumpbox.com/doc/runtime/faq/install_phpmyadmin[/url]

No problems encounted until I get to the step of :

Now to access PHPMyAdmin on your JumpBox just point your browser to http://jumpboxip/phpmyadmin. [/quote]

I replaced the "jumpboxip" with the ip address listed as the application IP (where I notmally get to my joomla site)

I get a 404 page not found error. How do I get myphpadmin to run?

Instructions for resolving the 404 issue

I had this issue as well. Here's how to fix it.

After following all the instructions and reaching the 404.

> sudo nano /etc/apache2/apache2.conf

Add the following line of code inside apache2.conf:
Include /etc/phpmyadmin/apache.conf

Restart apache and it should work.

Problems getting phpmyadmin

I try to follow the instructions, but get:-
sudo: apt-get: command not found

I can´t get past this. Is there something I am doing wrong?

I have my jumpbox installed on a Mac and am using the Terminal
