OSX 10.11 (aka El Capitan) changes the security model of OSX somewhat.
/usr/ is now completely off-limits *except* for /usr/local/ -- and my
personal preference is to avoid pushing the boundaries, so I would use
/opt/local/

(The whole subject of SIP is more Python-related than your specific
question IMO, at least for anyone who has intentions of distributing
applications.)
