Question on building from sources.

I have my QuickSilver and no internet connection. I have a few questions.
1. Do I download the latest for PowerPC(32bit) and then download the
sources according to the Makefile.
2. Will I need to skip checking the hash/md sum so that the
applications can build?
3. Has anyone else done this before? If yes, then what were your results?

I'm asking on two lists because:
1. It is a PowerPC based machine.
2. It will be an installation of current.

Thanks muchly.
