The Reinteract installer bundles many external dependencies. In general, I've
used standard Windows builds rather than compiling my own versions from scratch.

The list below gives the version and original download location of the
binary components I've included in the Reinteract installer. The
locatin of the corresponding source is listed as well. All files referenced
below are mirrored on this site in the:

 components/binaries
 components/sources

NOTE: matplotlib
   The standard matplotlib build depends on the Visual Studio runtime 
   library msvcp71.dll, which user's are expected to find on the
   net somewhere. Redistributing Visual Studio runtime libraries
   is possible with an appropriate EULA, but to avoid that, I rebuilt
   matplotlib myself. Instead of using the matplotlib tarball of
   standard dependencies, I built it against the libraries from the
   GTK+ distribution for windows. The patch used to build can be
   found in the components/sources directory alongside the original
   tarball.
