Installing MacPorts on a pure Darwin x86 64 bits system

[Jean-Michel Pouré]

Dear friends,

I would like to take more active development and help other Kdenlive
developers debug Kdenlive natively under Darwin system. Most of us are
using MacOsX. We cannot run multiple computers at the same time. It
costs too much time and energy.

Is there a suitable way to install MacPorts on a pure Darwin system?

Thanks in advance.
Jean-Michel
