For me, the latter is to be preferred since our default image for Macs includes some really old stuff that gets put on the path. This means that about 20-40 of the scons test fail since they think a tool is defined but the default environment can not run them since it is not on the environments path.

Setting up a good paradigm for tools would be a good idea here. Having
looked at a few tools, from what I can tell, no two tools use the same
approach to anything, and there are lots of arcane bits in some of them.
