I (finally) installed this patch to quit early if the perl path has
spaces. Thanks.

As for MKDIR_P and INSTALL, I guess it is somewhere in the
prerequisite/autoconf stuff. I suppose it would be rare that they would
be found in a path with spaces while perl was not, so I think it's ok to
let that go. --best, karl.
