This is probably going to be fixed by your work on making singular more
interruptable, but I just wanted to mention things.

$ überbenutzermache einpaketwerkzeug-hole install

The question arises whether openssl should be a standard spkg that is
installed if the openssl headers can not be found on the system. That
would be similar to the gcc spkg, which is standard but is only
installed if the gcc found on the machine is the wrong version (or the
user asks for its installation).

Cheers,
Simon

If we ship OpenSSL with Sage, we *certainly* violate the GPL.  IMHO, we
might still be violating the GPL with the optional package, but that's
not so clear.

Really we should get sage -i to work without ssl as long as you don't
download from a https url. In fact, nothing in Sage should depend on ssl
except for the notebook.

For the record, the next Sage version checks for ssl headers/libraries in
prereq and will recommend that you install it via your package manager
before the compilation starts.
