[Mailman-Users] Installing Mailman on OS X El Capitan--can’t find source of erroneous call of binary at /usr/share/mailman/mail/mailman

Thanks very much!

I looked through Defaults.py and found

PYTHON          = '/usr/bin/python'
PREFIX          = '/usr/local/mailman'
EXEC_PREFIX     = '${prefix}'
VAR_PREFIX      = '/usr/local/mailman'

This looks normal to me and is verbatim from Allan Herman's instructions, which get their configure call from Larry Stone's May 1, 2010, instructions (also on this mailing list):

./configure --prefix=/usr/local/mailman --with-cgi-gid=_www --with-mail-gid=_mailman

I can't find any reference to "--exec-prefix=" in config.log.

Nonetheless, I have not run into any contradictions. It appears that the choices for the locations of the various configuration files made when transitioning from Mac OS X Snow Leopard to Mac OS X Lion to OS X Mountain Lion have remained stable.

I kept getting the "Operation not permitted." error. I learned that this is due to System Integrity Protection (SIP), introduced in OS X El Capitan.
