I can confirm this works for my local builds as well (10.7.5). Spatialite 4
now seems to be mostly, if not completely, functional now. Thank you,
Juergen!

I, too, work with spatialite_gui as it is (I think) the best means for
working with spatialite dbs/tables. Unfortunately, it's gui is built off of
wxWidgets instead of Qt, i.e. an additional gui toolkit would need to be
installed with or alongside William's frameworks. However there is an easy
means of getting the latest versions of those, by using homebrew in an
isolated install directory [0].
