Yes, I was just about to send the following email:

I think just twisted, maybe openssl.
So I tried to strip the whole sage-...spkg package, but I didn't
manage to make it installable in the end -- almost everything depended
on everything (like rings, polynomials, NTL, etc.) - and it once
looked I managed to get rid of it, but it failed to install in the
end.
https://bitbucket.org/certik/sage-341alpha0/
The problem was that I needed to delete everything between the
installs, but I was just doing sage -b.
Tomorrow I am busy, but on Wednesday I'll try the other approach, just
take the notebook and put in things that are needed, that should be
fairly simple, hopefully. I will have to write my own setup.py
probably, but since that is needed anyway in the long term, it should
work.
Or maybe combinations of the above. I think I know understand a bit
what is needed for what.
