   3 # We put a fake "pycryptopp-0.5.13" package on the PYTHONPATH so that
   4 # the build system thinks pycryptopp-0.5.13 is already installed. Then
   5 # we execute run_trial.py. If the build system is too naive/greedy
   6 # about finding dependencies, it will latch onto the
   7 # "pycryptopp-0.5.13" and then will be unable to satisfy the
   8 # requirement (from _auto_deps.py) for pycryptopp >= 0.5.20 (or
   9 # pycryptopp >= 0.5.14, depending on machine architecture). This is
  10 # currently happening on trunk, see #1190. So with trunk, running
  11 # test-with-fake-pkg.py shows a failure, but with the ticket1190
  12 # branch, test-with-fake-pkg.py succeeds.
