The makefile will run a shell command to determine the location of the
python libraries. If an error occurs, for example if the system doesn't
have python installed on it, undefine PYLIB

This prevents undesired side effects such as installing man pages for
utilities that will not be installed and does not interfere with other
conditionals such as if test -n "${PYLIB]"
