In fact, I am getting an error. The first . "$configured_common_env" 
will print an error message, so the user should be informed of something 
going wrong.

You are right in that this should not happen. However, it may happen if 
the user decides to run the iotests from the source tree instead of the 
build tree if he/she is still used to the old way of invoking them. So I 
think, having a default common.env should solve this without creating 
new problems.
