There is a problem that isn't addressed: autoscan.

Whatever heuristic is appropriate for autoscan should equally apply to
an empty directory.

I can't think of an appropriate heuristic, but your message
"autoscan: Couldn't find configure.ac nor configure.in file
run /usr/auto*/bin/autoscan directly"
seems reasonable to me. (That is, that the user must explicity choose in
this case).
