It's not supposed to be --- at least, not unless you install it there
manually.
Please note also that this is not a generic breakage. What you need to
be asking is what in your particular environment is causing this failure.
I'm inclined to guess that it's specific to "make check"'s temporary
installation. Have you tried "make installcheck" to run against a
non-temp installation?
