Note that Dima's answer is somehow misleading, since downloading openssl
from the Sage mirrors does not require SSL.
Hence the following is still possible, without having openssl-dev as a
system prerequisite:
- check that openssl-dev (or equivalent) is installed system-wide
- if not:
- warn the user and suggest/recommend her to install it
- as an alternative, propose to download and install openssl from the
Sage mirrors via http
- build Sage
