Testing on a Mac turned up a problem that did not show up on linux.

SK and I agree that we are surprised by that.

Both bld = env['BUILDERS']['PDF'] and bld = env['BUILDERS']['DVI'] had
lines like
bld.add_action('.tex', LaTeXAuxAction)  # for DVI
bld.add_action('.tex', PDFLaTeXAuxAction) # for PDF
run from the initialization of two tools. This was a BAD thing.

That cured some test failures. For the rest I made all the TEX tests
initialize the environment with the os.environ PATH since the check
for the existence of the tools with where_is that looks on the system path.

So the tests still quietly exit if the tool is not on the system path
and now find if it is in a non-standard location like I have.
