yeah it's a sun4u which is a 64bit processor

Researching this I came acrossed some lists that said that not all apps
really benefit from being compiled 64bit. In some cases it leaves you
worse off since 64bit apps are more processor/memory/disk space intensive.
The consensus seems to be only a few apps such as the system kernel, gcc
should be compiled as 64bit apps.

This isn't any personal knowledge just what I got from what I've read. If
i'm wrong please correct me.

If I do need multiple copies of everything the paths will probably be a
