Yes, those are exactly the files I was missing. I think I did not 
specify the variant_dir for the original un-renamed folder names because 
scons was complaining about how a variant_dir cannot be under the 
original dir. I can understand why you cannot build "foo" under 
"foo/bar" since it would create a recursion nightmare but it seemed odd 
that you cannot simply use the exact original directory name as the name 
of the variant_dir; it's not exactly a variant if you do this ! The 
duplicate=0 was simply to avoid copying the source files. I did not 
think it applied to build targets but I see now that it makes sense; I 
had noticed some object files were not being copied to my variant folders.

Anyway, that is an interesting idea; I will try giving some dummy 
variant names for those original folders to see if it helps. However, it 
seems odd that some variant folders (e.g. ptscotch_dll) did receive the 
DLL; from what you suggest, only my original non-variant directories 
should get the files .... Since there are only 2 original folders with 
non-variant calls, I should be missing 4 DLLs out of 6 instead of just 2.
