PyROOT with root6 ACLiC Issues

[jfcaron3]

Hi, I've tried reporting this on ROOTTalk but haven't gotten anywhere. It looks like it might be MacPorts-specific. ROOTTalk post: ​http://root.cern.ch/phpBB3/viewtopic.php?f=14&t=18229

I tried using MacPorts provided ROOT 6.00.01 and I get the same behavior, so it's not my customized GSL & ROOT. This is still a problem on 6.06.00.

Steps to reproduce.

File tuple.C:

#ifndef __MAKECINT__
#include <tuple>
#endif
#include <array>
#include <utility>
int foo() {
  int a,b;
  std::tie(a,b)= std::make_pair(5,6);
  return a;
}

When running python2.7:

> python2.7
Python 2.7.11 (default, Dec  8 2015, 20:16:01)

clang: error: linker command failed with exit code 1 (use -v to see invocation)

When running root6:

$ root6
...
root [0] .L tuple.C+
Info in <TMacOSXSystem::ACLiC>: creating shared library /private/tmp/./tuple_C.so
root [1] .q

(Running python2.7 after root6 would make the python command succeed because the files are already there.)
