Dockerfile compile of bitcoin

[tofutim]

Thanks for your great work on bitcoin. I'm trying to use the Dockerfile to generate a Mac client. I now have copied the SDK to the SDKs folder, however, when I start I see errors like this:

Hint: If this hangs, you may want to try turning your guix-daemon off and on
      again.

Is this normal?

It does seem to be compiling now though...

It ultimately finished. I guess that's good!

Yes, these warnings are currently expected.
