I agree. Let's go for two packages (like many others do): one without
dependencies included, one with. I would, however, limit the first to
basic dependencies (sh.exe and other utils for scripts, tcltk) and not
include things such as R, PostgreSQL, etc.

We do however have to keep in mind the issue of licensing and distribution
of source code:

Thus, if we include more packages, we will have to keep more copies of the
used source code around... So this means tcltk and msys.

Would it be an envisageable option to build an installer which installs
the basic grass distribution and optionally downloads and installs other
packages from their respective websites if the user so choses ?
