Have you tried QGIS yet with Juergen's change to accept empty spatialite DBs?  It would be good to check if this works before trying Spatialite 4.1.

This is part of the postgis build, but can have its .so and headers files moved to a different location (I believe) because it only links to libgeos_c and libproj. However, I did not find liblwgeom-2.0.3.dylib in your install for postgis 2.0.3.

This would offer extra geometry functions to spatialite [0] (especially the MakeValid function) without requiring users to install the full postgres/postgis package.

Maybe.  It's getting messy.  But, PostGIS is GPL, and I'd rather keep the whole framework non-GPL.  So it would have to be the standard full Postgres+PostGIS install, but then the framework becomes dependent on PostGIS (directly) and Postgres (indirectly).

I did not have issues building libspatialite against default libxml2 on Lion (10.7.5), but spatialite-gui failed unless I built libspatialite against a newer 2.9.x version of libxml2 [2]. 2.9.x version is recommended (required?) for spatialite.

I saw this addition to 4.1 and expect to build it in.  Looks like Mt Lion also has xml2 2.7.  Another messy addition if using xml2 2.9, but license is OK.
