Correct.  SCons will only build what it's told to.  Default() is only used
when no command-line targets are specified.  And further, if there's no
Default(), everything under the current dir is built.

That should have worked.  Print out sampleLibraryEnv.Install(binDir,
sampleLibrary)) and see if it's a list containing your dll.
Do the printing like this:
 stuff=sampleLibraryEnv.Install(binDir, sampleLibrary))
 print [str(x) for x in stuff]
because the elements of the list are Nodes, and you need to print their
string representations.  If your DLL is in that list, then it should get
into the alias, and thence into the default (which of course is only used
if you don't specify a target).
