Wanting to compile the newest packages for Trinity Desktop, but I'm not sure what to do.

I just want to try compiling the newer packages. The prebuilt .txz packages are for version 14.0, and they are at 14.0.3 or something like that.
I'm using an IBM Netvista P4 with an SSD via PCI, so....not much performance difference between IDE and SSD IMO.

Anyway, obviously, I have to tar xvf the tarballs when I get them. After that, I'm not sure what to do.
