For (2), msp_kb2565063.msp is indeed a security patch and must be downloaded manually. I should add instructions somewhere about where to find it. (Search microsoft.com/downloads for that KB article number in the meantime.)
For (4), I would rather that scons looks in both places for the files. If it can't find a file in one place, search the other. The reason for this is because building Qt from source puts them in one place while downloading the pre-compiled DLLs puts them in the other and there's no telling which situation a particular user will have. (I just don't know enough python yet to add that intelligence or I would've done it already.)
Great work! Thanks for tackling these issues.
