Ah, I should say that the reason setting it correctly is tricky is
because it turns out it doesn't actually need to contain the
installation directory.  The important thing is that it contains the
directory where KConfig is installed, unless that *is* the installation
directory.  Basically, it only needs to be set if you're installing the
frameworks in different directories, like Jenkins does.
