Fail to install spack modules

[dpshelio]

Some just fail in the install after the install phase (maybe updating spack database?)

==> Installing GreatCMakeCookoff
==> Using cached archive: /home/dvd/Stuff/build/spack/var/spack/cache/GreatCMakeCookoff/GreatCMakeCookoff-2.1.9.tar.gz

/home/dvd/Stuff/build/spack/lib/spack/spack/package.py:1456, in build_process:
     60                        self.log()
     61    
     62                    # Run post install hooks before build stage is removed.
  >> 63                    spack.hooks.post_install(self.spec)
     64    
     65                # Stop timer.
     66                self._total_time = time.time() - start_time

whereas in other cases creates flags that spack doesn't know:
