The stuff in your sandbox should build on *any* Unix system. Tool X
shouldn't contain any dependencies on itself or any tools that require X
to already exist before they can be built: mathematically, the
dependencies should be a directed acyclic graph.
I note in passing here that there are a whole bunch of GNU tools in
existence that are supposed to help with all this (autoconf, automake
etc). It seems a pity that we can't use them.
