Dave Malcolm <[email protected]> added the comment:
Thanks.
The relevant code in setup.py is all wrapped with --pydebug:
if COMPILED_WITH_PYDEBUG or not have_usable_openssl:
All of my testing had been --with-pydebug.
Rebuilding without --with-pydebug leads to some interesting failures; as you
say, if OpenSSL has md5 support disabled, this isn't going to work unless the
_md5 module is manually enabled.
Notes on some of the failures seen:
