How to install dependencies not found in the repositories for JHBuild?

I have been following this guide in order to set up JHBuild. And I have got up to the бит which says to execute:

jhbuild sysdeps --install

However there is в slight problem because upon running that I have found that it is unable to locate some of the packages needed to продолжите. And now that it - installed all that it хан, this is the output from the command now (and every я украл I run it now this is the output):

emscripten is already the newest version.
