py27-spatialite does not build and install

[danrabin]

On a clean, freshly installed Macports, sudo port install py27-spatialite fails with

[excerpt from main.log] :info:build main.HeaderNotFoundException: cannot find proj_api.h, bailing out [end excerpt]

Dependency is on proj4, which doesn't seem to install the file in question, but not clear whether proj4 or py27-spatialite is at fault.
