I've added an user with name zenoss, and set export ZENHOME=/usr/local/zenoss in ~/.bashrc under /home/zenoss, and when using echo $ZENHOME, it could show /usr/local/zenoss

When install zenoss, I switched to zenoss and then run install.sh under zenoss-4.2.0/inst, when it tries to run Tests, the error occured.
