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