Maybe I'm just not reading it right, but isn't that just running the
exact same mkdir commands, just splitting it into two commands, and
making them optional based on the $(wildcard)? I'm still not clear what
the problem is.

Anyway, if this is an issue, then compal/paz00 and compulabl/trimslice
will need to be fixed for the SPL changes in the same way.
