Is El Capitan preventing me from getting the Perl module DBD::Oracle working?
I am using
  Mac OS X 10.11.3 El Capitan, 
  perlbrew 1.74 installed with cpanm &amp; App::perlbrew/0.74
  Perl revision 5 version 22 subversion 1 (installed via perlbrew)
  DBI -- 1.631
  DBD::Oracle VERSION: 1.74
  Oracle InstantClient 11.2.0.4.0 installed at /usr/local/lib/oracle/instantclient_11_2

I can confirm that the only way, so far, I have been able to get DBD::Oracle to work is by disabling SIP (http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x/). Any other way I've tried results in the error "failed: ERROR OCIEnvNlsCreate. Check ORACLE_HOME (Linux) env var ...".
