You will need a C compiler if you're building the
distributions from the sources. However,
as with all such repositories, the
uwinnipeg repository has
Win32 ppd packages containing pre-compiled binaries, so
you don't have to compile them yourself.
See, in particular,
A guide to installing modules for Win32
for how to use ppm, including how to add a repository
to the list of repositories ppm will use to install
packages.
