# The install steps for p4lang/PI and p4lang/behavioral-model end
# up installing Python module code in the site-packages directory
# mentioned below in this function.  That is were GNU autoconf's
# 'configure' script seems to find as the place to put them.

# On Ubuntu systems when you run the versions of Python that are
# installed via Debian/Ubuntu packages, they only look in a
# sibling dist-packages directory, never the site-packages one.

# If I could find a way to change the part of the install script
# so that p4lang/PI and p4lang/behavioral-model install their
# Python modules in the dist-packages directory, that sounds
# useful, but I have not found a way.

# As a workaround, after finishing the part of the install script
# for those packages, I will invoke this function to move them all
# into the dist-packages directory.
