[Scons-dev] detect vs. where_is

[Managan, Rob]

Since I am guilty of building tests by copying from existing ones I suppose I should ask this question.

Is there a good reason why tests tend to use test.where_is('my program') instead of test.detect('my program') ???

I ask since where_is uses the os.environ path and detect uses the path set up by the default environment. 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.
