It was...

will descend into that directory and build/install the compat libs.

After digging around the 6.x and newer source trees, it appears that the 
ability to build the old libraries is gone.  If it's not gone, it has 
moved to a location I can't find. :)  If you go directly from 4.x to 6.x, 
the compat4x port in misc is how you get your libs.

Correct?

Thanks,
