Install stable latest gcc 4.4.x on a workstation (Kubuntu 9.04)

[Tim]

Hi, I wonder if someone by any chance happen to know how to install a stable latest gcc (4.4.x) for a workstation under Kubuntu 9.04?

The reason I need gcc 4.4.x is that I would like to use Collapse in OpenMP 3.0 which is only supported in GCC 4.4 and later version. 

Stability is important since my administrator would like to make it work on a workstation shared by many people at work. But I have seen so many reports about the failure to install a stable gcc 4.4.x in the past few months. For example, I saw this somewhere online:

    sudo apt-get install gcc-snapshot

which as gcc snapshot's website says is not a stable one.

So I wonder if there is some way that can install a stable latest gcc (4.4.x) for a workstation under Kubuntu 9.04? Even gcc 4.4.0 is fine as long as it is stable and I assume it to have OpenMP 3.0. Or should I wait till a stable release of gcc 4.4.x on Kubuntu 9.04 is out? 

Another question: is building gcc 4.4.x on someone's Home directory from its source a good choice? Is it possible to not using root?

Really appreciate your suggestion!

Thanks and regards!
