Sure. No problem. Busy here as well.

Attempt at using "Distribute" (that was supposed to be be next unifying
thing for package distribute... but might not be in the end - package
distribution with Python is definitely not suffering from monotony).
Just ignore it, I'll take it out for the release.

It does, but only at run time.
Building is a more advanced operation (and I filtering candidate that
can't edit the %Path% out ;-) ).

R likes mingw better, if I remember right. There are ever changing
requirements about *the* right combination of tools for building R and
packages and you will likely need them (or a subset thereof).

R-2.9 on my end, I think.
