Old hardware, old software, how much of the world is running on both? Just spent far too much of my saturday in a vain attempt to install MT on a friend's website, casting myself into dark caverns of antique RedHat with some weird OS/X-some-such perl5 lib grafted on it by some long forgotten smart while not being clever techie who deleted everything divinely divined as unessential.
The deeper I dug, the worse it got.
I wrote their tech support to basically send my condolences: It has been so long since their last update, it's no longer a matter of a simple upgrade, it means a whole new installation, and that means new applications because the old ones will get broken.
I'm guilty too; little Kato under my desk is the last resting place for old parts before the landfill, used to keep our print server and wlan alive.
Kato's running the last RH I ever received under the RH beta-review plan, it's running the winston beta of 7.0, and it's broken in lots of spots, but the fix is going to mess up so many things, frankly, I just don't have the time for it. There must be a lot of shops in my position, edge servers, old servers and just no time. But it's a ticking time bomb, I know it: The longer I wait, the longer its teeth get.
we need a Deshimaru O/S:
Keep your package manager network transparent, and all of the shared libs of the universe pass through them. Close them, and all you can run is a bit of grit. 
Our life has no end in just the way in which our visual field has no limits.
