Ouch, that brings back another UBUNTU problem. It does not install
Java (are most programs) in /usr/bin. It installs them in /usr/bin
under another name, or eleswhere. Then it links /etc/alternatives/
<name> to them. Then it links /usr/bin/<name> to /etc/alternatives/
<name>.
For example:
>ls -l /usr/bin/java
lrwxrwxrwx 1 root root 22 Mar 2 2009 /usr/bin/java -> /etc/
alternatives/java
>ls -l /etc/alternatives/java
lrwxrwxrwx 1 root root 36 Oct 13 2009 /etc/alternatives/java -> /usr/
lib/jvm/java-6-sun/jre/bin/java
Lots of extra overhead and confusion.
It even is worse because for simple binaries, such as mpg123 it does
it too. If you want to have mpg123 and mpg321 both installed, it won't
and gets confused. To answer the question before it is asked, I need
mpg123 as there is a bug in mpg321 and it was easier to use the other
program than go through the bug tracking system for a bug I'm probably
the only person who ever noticed.

in the Wikipedia.
