I've spent more than an hour trying to create a google account so that I can report serious problems I'm having with compiling the sagemath source code but google won't let me create an account. Its very unreasonable for sagemath to require users to create a google account just to get support. Why not use github or an independent website? Just because they are closely tied with google doesn't mean they have to force users to bend to their will.
Any way, the problem is that I get this error when trying to build sagemath on fedora 28:
Error building Sage.
