I'm a little confused by the changes. It seems now that 
CUSTOM_CONFIG_DIR must always be set when calling autogen.sh, to do any 
custom configure generation. So where previously I would run "bash 
common/autoconf/autogen/sh" and it would handle open and custom, now it 
will only handle open unless CUSTOM_CONFIG_DIR is set. And the 
expectation is now that I would invoke the custom autogen.sh to also 
handle the open case - is that right?

Thanks,
David
