In Windows it's necessary to include most of the libs in the package. Since they commonly are LGPL I reckon that we must also make sure there's a source package (for the libs) available along with the binary installer. I haven't done anything yet to create such a package. It wouldn't be enough to simply have a list of download links to the respective web sites for the libs, right?
You are correct that it wouldn't be enough strictly speaking. We must be able to deliver the exact source packages used to produce the libs.
