Or am I missing something?

The method where_is() accepts a "path" as second argument, that is used 
for searching if specified. So you could call TestSCons.where_is() with 
the stripped down PATH variable as well. This should then give identical 
results...haven't tried though. ;)

Russel,

I think the alternative is TestSCons.TestSCons().detect_tool(tool). A
quick look at the source makes it look like it expects a single tool name
to be given. It seems to use an environment created for that tool and uses
its path.
