[petsc-dev] PTScotch 6

[Jose E. Roman]

There is a new version of PTScotch. I tried configuring with --download-ptscotch=https://gforge.inria.fr/frs/download.php/31832/scotch_6.0.0_esmumps.tar.gz

It works on Linux with the patch below (note the missing whitespace should have been fixed in 3.3).
On Mac I had a compilation problem related to pthreads. After commenting out these lines in PTScotch.py it builds well.
    if self.libraries.add('-lpthread','pthread_key_create'):
      self.cflags = self.cflags + ' -DCOMMON_PTHREAD'
      ldflags += ' -lpthread'
