Thanks for this very useful information! We should put this somewhere for
later reference.

No, there is no -debug option in 5.x, -verbose is all there is, but the
build + install scripts are available and may be of use for analyzing
the exact build steps.

Yes, if all dependencies are already available and installed. "-purge" is a
separate operation and can not be combined with the step of installing
an egg. "-no-install" will leave the build results in the cache, so you have
to peel what you need out of that location.
