Thank you, that was a big help.
There was a .configure_done.prusa-slicer._usr_local but no .build
subdirectory.  If I remove the .configure_done and do a make configure
it correctly creates the .build subdir and populates it, but due to an
error it doesn't complete and so leaves no .configure_done.

So... I can continue work from here, thanks.
What's not clear is how the .configure_done got written in the first place;
I can't reproduce it.

Thanks,

Gary
