Yes, I found the same (and had a strong feeling of deja vu...)

I discovered that the machine this is on had "lost" its openssl-dev
package.  I don't know how, but it had also lost g++ and gfortran at
the same time.  (This is ubuntu: it appears that "sudo apt-get
autoremove" removed more than obsolete unused packages).

So I reinstalled openssl-dev using the package manager, then did what
you suggest above (without the ssl), and am now rebuilding all the
things which depend on python2.

I would prefer it if the build process would not proceed without
openssl;  there was some complicated reason why it is not a
prerequisite, but I cannot remember the details.  Since pip is now
standard, and required openssl to work properly, ....?
