Thanks, I am glad you like it so far!

Let me see if I get this straight: you already have MSYS2/MinGW
installed but also installed build2-baseutils (and build2-mingw)?
Plus you had your MSYS2 installation in PATH?

If so, then, yes, things will most likely get rough (due to DLL
incompatibilities). In this case you should either just use your
MSYS2/MinGW to both build build2 and to provide the base utilities
(like gzip) or make sure that your own MSYS/MinGW in not in PATH
when building and using build2.

Yes, currently there are a few ad hoc steps required to make it
buildable. Eventually we will clean it all up but for now I've
packaged you a distribution (note that there are no packages
published on stage.build2.org yet so this will have to be a
local-only build):

Yes, we will definitely do this once we work out all the kinks.
Also, soon, we will start automatic staging of master so that
will be another, easier option.

Thanks for the feedback,
Boris
